Interaktivní výukové modely vodohospodářských staveb pro Hydrotechnickou laboratoř Stavební školy ve Vysokém Mýtě / Interactive Instructional Models of Water Management Structures for Hydro-technical Laboratory of the High School of Civil Engineering in Vysoké Mýto

Požárová, Miroslava January 2016 (has links)
In 2014 a new Hydro-technical laboratory was built at the High School of Civil Engineering in Vysoké Mýto. The laboratory’s hydraulic circuit is equipped with a reserve line enabling independent standing models of hydro-technical structures to be connected. Two interactive instructional models are designed for this laboratory. The first is a model of a concrete dam. The dam is equipped with one bottom outlet, a hydraulic power plant and an emergency spillway crest gate. The discharge part of the model is equipped with a downflow baffle for regulating the tailwater level and a measuring weir enabling the flow rate to be measured at the discharge point from the model. The total capacity of the model is 10 l/s. The second model is a model of a weir structure. The weir structure consists of a controlled segment sluice gate weir composed of three sections. The model includes a one-nave lock chamber and hydraulic power plant. The tailwater level can also be regulated using a downflow baffle. The total capacity of this model is 20 l/s. The models can be used for teaching the subjects of hydraulics, hydrology and hydro-technical structures. They can be used to demonstrate various hydraulic phenomena and to describe individual functional objects using specialist terminology. This thesis contains the full project documentation for both proposed models, including hydro-technical calculations and text appendices.

Experimental Characterization of Baffle Plate Influence on Turbulent and Cavitation Induced Vibrations in Pipe Flow

Holt, Gavin J. 14 June 2011 (has links) (PDF)
Turbulent and cavitation induced pipe vibration is a large problem in industry often resulting in pipe failures. This thesis provides an experimental investigation on turbulent flow and cavitation induced pipe vibration caused by sharp edged baffle plates. Due to large pressure losses across a baffle plate, cavitation can result. Cavitation can be destructive to pipe flow in the form of induced pipe wall vibration and cavitation inception. Incipient and critical cavitation numbers are design points that are often used in designing baffle plate type geometries. This investigation presents how these design limits vary with the influencing parameters by exploring a range of different baffle plate geometries. The baffle plates explored contained varying hole sizes that ranged from 0.159 cm to 2.54 cm, with the total through area, or openness, of each baffle plate ranging between 11% and 60%. Plate thickness varied from 0.32–0.635 cm. Reynolds numbers ranged from 5 x 10^4 -85 x 104. The results show that the cavitation design limits are function of size scale effects and the loss coefficient only. The results also show that the loss coefficient for a baffle plate varies not only with total through area ratio, but also due with the plate thickness to baffle hole diameter ratio. Pipe wall vibrations were shown to decrease with increased through area ratio and increased thickness to diameter ratios. An investigation was also performed to characterize the attenuation of vibration in the streamwise direction of a baffle plate. It was show that the attenuation was largely effected by the presence of cavitation. Attenuation was shown to be a function of the geometry of the baffle plate. This work resulted in empirical models that can be used for predicting pipe vibration levels, the point of cavitation inception, and the streamwise distance where the attenuation of vibration levels caused by a baffle plate occurs.

Moderní technologické prvky pro trubkové výměníky tepla / Modern technological elements for tubular heat exchangers

Plánková, Tereza January 2020 (has links)
The aim of this diploma thesis is to get acquainted with modern technological elements currently used in shell-and-tube heat exchanger in the shell-side and tube-side, thermal-hydraulic calculation of selected elements and comparison of thermal-hydraulic properties with classically used competing technological elements. The work deals mainly with EM baffle in the tube-side and tube inserts like the twisted tape type (and its modifications) and coiled wire in the tube-side. The theoretical part is focused on acquaintance with classical technological elements in shell-and-tube heat exchanger and with basic thermal-hydraulic calculations, practical part then on acquaintance with modern elements and thermal-hydraulic calculation of selected elements. These calculations are then compared with the results of the thermo-hydraulic calculation of similar elements.
