A study of bioaerosol sampling cyclones

Moncla, Brandon Wayne 17 February 2005 (has links)
A wetted wall cyclone using an airblast atomizer upstream of the inlet was designed as an improvement of a wetted wall cyclone developed by White et al. in 1975, which uses liquid injection through a port on the wall of the cyclone inlet. In the course of this project, many changes to different aspects of the White-type cyclone design and operation were considered. These included inlet configuration, liquid delivery, porous media, surface finishes and coatings, outlet skimmer design, and cyclone body length. The final airblast atomizer cyclone (AAC) design considered has an aerosol-to-hydrosol collection efficiency cut-point of 1.6 µm with collection efficiencies at 2 and 3 µm of 65% and 85%, respectively. The efficiency reported for the White-type cyclone for single Bacillus globigii spores that have a particle size of about 1 µm was approximately 81.8%. The aerosol-to-aerosol transmission efficiency for the AAC configuration was found to be approximately 50% for 1 µm diameter particles as compared with 70 – 100% for the White-type cyclone. A time response test was performed in which the White-type (ca. 2003) cyclone had an initial response of 3 minutes for a condition where there was no liquid carryover through the cyclone outlet and 8 minutes on average with hydrosol carryover. The decay response of the White-type cyclone was 1.25 minutes for non-liquid carryover conditions. The AAC had an initial response of 2.75 minutes and a decay response of 2.5 minutes. The shortened version of the AAC had an initial response of 1.5 minutes and a decay response of 1.25 minutes. There was no liquid carryover observed for any tests of this cyclone configuration. Power consumption tests were performed comparing pressure drops across different variations of White-type cyclones (circa 2003 and 1999) including a variation with an electrical discharge machined (EDM) inlet profile, that reduces the pressure drop at a nominal air flowrate of 780 L/min from 18 inH2O for the basic White-type cyclone (ca. 2003) to 16 inH2O with use of the EDM inlet. Two different variations of White-type cyclones were found to have pressure drops of 25 inH2O and 18 inH2O at an air flowrate of 780 L/min.

Patterns and behaviors of global tropical cyclones

黃詩偉, Wong, Sze-wai January 2013 (has links)
This study examines the global tropical cyclones (TC) patterns and distributions from 2001-2010. The objective of the study was to find out the possible relationship between the TC activities between different oceans. The TC track record was obtained from the Hurricane Data Centre at Unisys Weather webpage and it has been plotted and transferred to a spread sheet format. By combining the data with the oceanic maps from General Bathymetric Chart of the Oceans (GEBCO) digital Atlas, we could conclude the trend and distributions of the TC in each year. Various data were also collected from the National Oceanic and Atmospheric Administration (NOAA), Climate Prediction Center and Bureau of Meteorology (BOM) so as to further explain the TC relationships in different regions. It is concluded that the TC distributions has no significant relationship between oceans in the same hemisphere but it shows certain pattern throughout the ten years record. / published_or_final_version / Applied Geosciences / Master / Master of Science

An Assessment of Cyclone Mitigation and Management Policies of Bangladesh: A Focus on Early Warning Systems

Bisson, Tiffany 02 May 2012 (has links)
This study was conducted in Dhaka and Cox's Bazar, Bangladesh to examine grass-roots cyclone vulnerability and the government policies and cross-scale linkages that address this vulnerability. After conducting surveys with local villagers, it was determined that while the majority of people understand the cyclone is impending, the options available to them for safe evacuation are limited, as there are not enough cyclone shelters, not all shelters are maintained and in usable condition. Also, budget constraints and improper relief distribution impair the country's ability to mitigate cyclone vulnerability. It was realized that the NGOs act not only as a liaison between villagers and government, but they are the major stakeholder in local level capacity building. It was recommended that additional NGOs for a presence in Cox's Bazar to alliviate the pressure felt by the Cyclone Preparedness Program and Red Crescent, but also to increase the ability of local villagers to work with disaster management stakeholders that are not government representatives.
