EXPERIMENTAL AND CFD STUDY OF EFFUSION COOLING IN AN S-BEND DIFFUSING PASSAGENg, BILLY CHOK NAM 23 December 2013 (has links)
This thesis presents an experimental and computational fluid dynamics (CFD) study on a rectangular S-bend with straight and diffusing passages with passive effusion cooling. Experimental tests were performed at both cold and hot flow conditions over a range of Reynolds numbers from 2.5e5 to 4.5e5. Hot flow testing was conducted with the primary flow temperature up to 300 °C.
Severe backpressure penalties occurred with full-surface passive effusion injection in cold flow tests. Moderate penalties occurred with reduced surface coverage whereby the performance was affected by the S-bend secondary fields with injection at different locations. High surface cooling effectiveness with full-coverage of cooling film was measured; the impacts from the S-bend secondary flow fields were measured to be minimal.
The CFD study revealed the importance of using experimental flow boundary conditions for simulations. Using the standard k-ε model with wall functions was confirmed as appropriate for simulating the S-bend flow with effusion cooling.
A coarse-grid CFD methodology using a porous wall boundary condition to simulate the effects of effusion cooling was investigated. From a design perspective, this model is preferable for quantifying the injection flow rate since the actual mass flow rate is not known. Comparison to the alternative solution using uniform mass flow boundary conditions showed that both models incorrectly predicted the momentum. The porous wall model, however, is promising for practical design applications of S-duct flow fields with effusion injections. / Thesis (Ph.D, Mechanical and Materials Engineering) -- Queen's University, 2013-12-23 14:20:32.38

Continuous Tracking of Lava Effusion Rate in a Lava Tube at Kilauea Volcano Using Very Low Frequency (VLF) MonitoringFreeman, Richard A. 01 May 2014 (has links)
Measurement of lava effusion rates is a key objective for monitoring basaltic eruptions because it helps constrain geophysical models of magma dynamics, conduit geometry, and both deep and shallow volcano processes. During these eruptions, lava frequently travels through a single "master" lava tube. A new method and instrument for continuously monitoring the crosssectional area of lava streams in tubes and estimating the instantaneous effusion rate (IER) is described. The method uses 2 stationary very low frequency (VLF) radio receivers to measure an unperturbed VLF signal and the influence of highly conductive molten lava on that signal. The difference between these signals is a function of the cross-sectional area of molten lava and the IER. Data from a short test of the instrument are described. This methodology represents a breakthrough in the continuous monitoring of IER because it provides higher temporal resolution than competing methods at a fraction of the cost.

Estudio de la angiogénesis en la patología pleural y su asociación con los marcadores de actividad neutrofílica, el sistema de la fibrinolisis y la matriz extracelularRuiz Ruiz, Eva 26 June 2004 (has links)
Introducción: Los derrames pleurales (DP) son una patología común, aunque su fisiopatología no está del todo aclarada. El sistema de la angiogénesis se ha visto implicado en procesos inflamatorios y neplásicos, pero ha sido poco estudiado en el espacio pleural. Objetivos: 1) Analizar los niveles pleurales y plasmáticos de factores activadores e inhibidores de la angiogénesis en diferentes categorías de DP. 2) Estimar su asociación con los marcadores bioquímicos habituales, el recuento celular, los marcadores inflamatorios, el sistema de la fibrinolisis y el de las metaloproteinasas. 3) Estudiar su asociación con la presencia de complicaciones pleurales en los DP infecciosos. Pacientes y método: 21 pacientes de cada uno de los siguientes DP: empiema o paraneumónico complicado, paraneumónico no complicado, tuberculoso, neoplásico y trasudado. Se determinaron en sangre y pleura los marcadores bioquímicos habituales (glucosa, proteínas, ADA, LDH, pH), celularidad (leucocitos y recuento diferencial), marcadores inflamatorios (elastasa, IL-8, TNF-alfa), sistema de la fibrinolisis (activadores del plasminógeno u-PA, t-PA e inhibidores PAI-1, PAI-2), sistema de las metaloproteinasas (MMP-2, MMP-9 y sus inhibidores TIMP-1, TIMP-2) y sistema de la angiogénesis (activadores factor de crecimiento endotelial vascular (VEGF total y libre), factor de crecimiento fibroblástico básico (b-FGF) e inhibidores endostatina y trombospondina-1 (TSP-1). Paquete estadístico: SPSS.Resultados: Los niveles de VEGF y b-FGF fueron más altos en los exudados que en los trasudados (p < 0.001) y en los empiemas y paraneumónicos complicados que en los no complicados (p < 0.001). La endostatina no mostró diferencias significativas en los diferentes grupos de DP excepto dentro de los paraneumónicos, donde los niveles fueron superiores en los no complicados que en los empiemas y paraneumónicos complicados (p = 0.002). La TSP-1 mostró niveles superiores en los exudados que en los trasudados y en los empiemas y paraneumónicos complicados que en los paraneumónicos no complicados (p < 0.001). En los exudados pleurales observamos una correlación positiva entre VEGF, b-FGF y TSP-1 y los niveles bajos de glucosa y de pH y los niveles altos de LDH, la IL-8, la elastasa y el TNF-alfa. En los exudados pleurales observamos una asociación positiva entre VEGF, b-FGF y TSP-1 y los PAIs y la MMP-9 y una asociación negativa con el t-PA y la MMP-2. Excepto para la TSP-1, los factores implicados en la angiogénesis presentaron niveles superiores en pleura que en plasma. Excepto para la endostatina en los DP paraneumónicos, no se evidenció correlación entre los niveles pleurales y plasmáticos de los factores implicados en la angiogénesis. Los DP paraneumónicos con cifras más altas de VEGF, b-FGF y TSP-1 presentaron mayor incidencia de paquipleuritis.Conclusiones: 1) Los DP exudados muestran valores más elevados de VEGF, b-FGF y TSP-1 que los trasudados, siendo el grupo de los empiemas y paraneumónicos complicados los que presentan los niveles más altos. Asimismo no existe correlación entre los niveles pleurales y plasmáticos, sugiriendo una respuesta compartimentalizada a nivel pleural. 2) En los exudados pleurales existe una correlación positiva entre VEGF, b-FGF y TSP-1 y los niveles bajos de glucosa y de pH, los niveles altos de LDH, los marcadores de inflamación, los PAIs y la MMP-9 y una correlación negativa con el t-PA y la MMP-2. 3) Los DP bacterianos paraneumónicos con cifras más altas de VEGF, b-FGF y de TSP-1 presentan mayor incidencia de paquipleuritis y podrían ser predictores de la presencia de complicaciones pleurales tardías. 4) Con este trabajo se aportan datos novedosos del papel de la angiogénesis en la fisiopatología de los DP exudados y de su asociación con la inflamación, el sistema de la fibrinolisis y la matriz extracelular. / Introduction: Pleural effusion is a common clinical entity, though its pathophysiology is still uncertain. The angiogenesis system has been implicated in inflammatory and neoplastic processes; nevertheless, it has been little studied in relation to the pleural space. Aims: 1) To analyze pleural and plasma levels of the activator and inhibitor factors of angiogenesis in the various types of pleural effusion; 2) To estimate the association of these factors with related biochemical markers, leukocyte count, inflammatory markers, fibrinolysis system parameters and metalloproteinases; and 3) To study the association between the angiogenesis factors and the presence of complications in infectious pleural effusions. Patients and method: Samples from 21 patients with each of the following etiological types of pleural effusion were studied: empyema or complicated parapneumonic, non-complicated parapneumonic, tuberculous, neoplastic and transudative effusions. Plasma and pleural fluid related biochemical markers (glucose, proteins, ADA, LDH, pH), cellularity (leukocyte count and differential count), inflammatory markers (elastase, IL-8, TNF-alpha), fibrinolysis system (plasminogen activators-PA, t-PA-and inhibitors-PAI-1, PAI-2), metalloproteinase system (MMP-2, MMP-9 and their inhibitors, TIMP-1, TIMP-2) and angiogenesis system (activators-total and free vascular endothelial growth factor (VEGF), basic fibroblastic growth factor (b-FGF)-and inhibitors-endostatin and thrombospondin-1 (TSP-1). Statistical package: SPSS.Results: VEGF and b-FGF were higher in exudates than in transudates (p<0.001) and in complicated parapneumonic patients and empyema than in non-complicated parapneumonic patients (p<0.001). Endostatin showed no significant differences in the various effusion groups, except the parapneumonic, where levels were higher in the non-complicated than in the empyema and complicated parapneumonic patients (p=0.002). TSP-1 showed higher levels in the exudates than in the transudates and in complicated parapneumonic effusions and empyema than in non-complicated parapneumonic effusions (p<0.001). In pleural exudates there was a positive correlation of VEGF, b-FGF and TSP-1 with low glucose and pH and high LDH, IL-8, elastin and TNF-alfa. Furthermore, VEGF, b-FGF and TSP-1 showed a positive association with PAIs and MMP-9 and a negative association with t-PA and MMP-2 in pleural exudates. With the exception of TSP-1, the factors implicated in angiogenesis presented higher levels in pleural fluid than in plasma. Except for endostatin in parapneumonic PE, there was no correlation between pleural and plasma levels of the angiogenesis factors. Parapneumonic PE, which showed highest values of VEGF, b-FGF and TSP-1 presented a higher incidence of pachypleuritis.Conclusions: 1) Exudative pleural effusions showed higher VEGF, b-FGF and TSP-1 values than transudative effusions, with the empyema and complicated parapneumonic groups displaying the highest values. There was no correlation between pleural and plasma concentrations, suggesting a compartmentalized response at the pleural level. 2) Exudates showed a positive correlation of VEGF, b-FGF and TSP-1 with low glucose and pH, and high LDH, inflammation markers, PAIs and MMP-9, and a negative correlation with t-PA and MMP-2. 3) Bacterial parapneumonic effusions with higher levels of VEGF, b-FGF and TSP-1 presented a higher incidence of pachypleuritis and could be predictors of late-onset pleural complications. 4) This study provides new data on the role of angiogenesis in the pathophysiology of exudative pleural effusions and on the association between angiogenesis and inflammation, the fibrinolysis system and the extracellular matrix.

Toracoscopia em crianças com derrame parapneumônico complicado na fase fibrinopurulentaFreitas, Sergio Luiz Oliveira de January 2006 (has links)
Introdução: Apesar de a toracoscopia ser o procedimento preconizado em crianças com derrame pleural parapneumônico complicado (DPPC) na fase fibrinopurulenta, a grande maioria dos trabalhos citados na literatura é de relato de casos ou revisão de pequeno número de pacientes. Este estudo interinstitucional foi realizado para determinar a eficácia deste procedimento em número significativo de crianças com DPPC na fase fibrinopurulenta. Métodos: Estudo retrospectivo de 99 crianças (0,4 a 11 anos; idade média 2,6 anos) submetidas à toracoscopia para tratamento de DPPC na fase fibrinopurulenta, operadas em três hospitais diferentes e com mesmo algoritmo de tratamento, no período de novembro de 1995 a julho de 2005. Resultados: A toracoscopia foi eficaz em 87 crianças (87%); 12 (13%) necessitaram de outro procedimento cirúrgico - 6 novas toracoscopias e 6 toracotomia/pleurostomia. O tempo médio de drenagem após a toracoscopia foi de 3 dias naqueles em que a toracoscopia foi efetiva e de 10 dias nos reintervidos (P < 0,001). Todos resolveram a infecção pleural. As complicações da toracoscopia foram enfisema subcutâneo na inserção do trocater em duas crianças (2%), infecção da ferida operatória em outras duas (2%), sangramento pelo dreno torácico em 12 (12%) e fístula bronco pleural em 16 (16%). Nenhuma necessitou intervenção cirúrgica, Conclusões: A efetividade da toracoscopia em crianças com DPPC na fase fibrinopurulenta foi de 87%. O procedimento mostrou-se seguro, com baixa incidência de complicações graves, devendo ser considerada como primeira opção em crianças com DPPC na fase fibrinopurulenta. / Introduction: Although Thorachoscopy being a procedure used to treat children with complicated parapneumonic pleural effusion (DPPC) in fibrinopurulent stage, most of the works presented in literature are case reports of only a few patients. The purpose of this work is to carry on a cross institutional study to determine the method’s effectiveness on a significant number of children with DPPC in its purulent stage. Methods: This is a retrospective case study of 99 children (ages 0,4 to 11; average age 2,6), from November 1009 to July 2005, submitted to thorachoscopy for the treatment of DPPC in fibrinopurulent stage, operated in three different hospitals and with the same treatment algorithm. Results: Thorachoscopy was effective for 87 children (87%). 12 (12%) needed to be submitted to another surgery – 6 to another thorachoscopy and 6 to thorachotomy/pleurostomy. The average draining time after thorachoscopy was 3 days for those whose thorachoscopy was effective and 10 days for those who were submitted to a new surgery (P< 0,001). In all cases, the pleural infection was successfully treated. Complications of the thorachoscopy were subcutaneous emphysema in the trocater insertion on two patients (2%), infection of the surgery incision on two other patients, bleeding through drain on 12 patients (12%) and bronchialpleural fistula on 16 patients (16%). None of them needed surgical treatment. Conclusion: The effectiveness of thorachoscopy on children with DPPC in fibrinopurulent stage was 87%. The procedure had low incidence of serious complications, and should be considered the first treatment option for children with DPPC in fibrinopurulent stage.

Accuracy and Added Value of Triage Beyond Segregating Potentially Neoplastic Effusions in Immediate Wet PreparationArabi, Haitham, Yousef, Nida, Han, Liying, Bandyopadhyay, Sudeshna, Feng, Jining, Al-Abbadi, Mousa 01 January 2009 (has links)
Objective: To study the accuracy and value of immediate wet preparation (WP) procedure on effusion and washing cytologic specimens. Study Design: Two hundred specimens were identified over 3 months in our cytology laboratory, including 102 pleural effusion, 59 peritoneal effusion, 28 pelvic washing and 11 pericardial fluid specimens. WP slides were prepared, stained with toluidine blue (TB) and evaluated. Findings were reported as negative, suspicious or positive for malignant cells. For negative specimens, the remaining prepared slides were stained together. For suspicious or positive interpretation, slides were stained separately. Accuracy and additional benefits from this immediate triage step were studied. Results: Interpretation of slides resulted in 152 negative, 34 positive and 14 suspicious for malignancy. Analysis for additional values resulted in immediate interpretation relayed to clinicians, additional fluid centrifuged for adequate sediment in samples with scant cellularity, selection of bloody specimens for acid washing procedures, selection of cases to optimize cell block preparation when pivotal histologic evaluation or immunohistochemistry was anticipated and selection of cases for potentially needed ancillary studies. Accuracy, sensitivity, specificity and positive and negative predictive values were high. Conclusion: WP using the TB is accurate, sensitive and highly specific and has considerable value beyond segregating potential neoplastic cases.

Indwelling Pleural Catheters Versus Chemical Pleurodesis for Managing Malignant Pleural Effusions: A Population-Based Study and Real-World Economic Evaluation ProtocolKwok, Chanel 28 June 2023 (has links)
There is limited data on mortality, health service use and costs following treatment of malignant pleural effusions (MPE) in the real-world setting.
We performed a retrospective population-based study using health administrative data of adults with indwelling pleural catheter (IPC) insertion (n=4,574) or pleurodesis (n=1,235) for MPE between 2015 to 2019. Inverse probability of treatment weighting using the propensity score was performed to adjust for baseline characteristic imbalances.
After weighting to balance on baseline characteristics, there was no significant difference in post-procedure mortality between individuals receiving IPCs and pleurodesis, with IPCs inserted significantly later after an initial cancer diagnosis. IPCs with home nursing drainage were associated with reduced subsequent health resource use and healthcare costs compared to pleurodesis. A protocol was developed for a future economic evaluation to compare the cost-effectiveness of the procedures. This thesis provides the foundation for further research to help optimize the treatment of individuals with MPEs.
