Measurement of capture efficiency of the reinforced slot exhaust system with a workbench
Šíp, Jan ; Zaremba, Matouš (referee) ; Pech, Ondřej (advisor)
The aim of this bachelor thesis is an experimental research on the efficiency of enclose reinforced slot exhaust hood situated over a workbench in the case of different ratios of momentum flux of supplied and the exhausted air flows. Exhaustion efficiency was also measured during the situation when the exhaust hood works as a classical one, i.e. without air supplied by radial slot. The workbench is situated on the upper edge of the exhaust slot opening. For measuring of the exhaustion efficiency was used a tracer gas method, such as trace gas was used carbon dioxide. For data evaluation was used the software Surfer. In the conclusion there are processed measurement uncertainties.

Influence of location of reinforced slot exhaust hood above work table on capture efficiency
Winkler, Martin ; Pech, Ondřej (referee) ; Pavelek, Milan (advisor)
The present thesis explores the reinforced exhaust slot system above work table. Its objective was to measure the capture efficiency in front of the suction extension in various elevation levels of the workbench, taking into consideration four mobility ratios, while in the first case we performed traditional suction. The thesis also presents the results of capture efficiency measurements recorded in figures and tables of measured values. The conclusion analyzes the uncertainty in performed measurements.
