Original abstract
The contribution deals with the interferometric visualization and a smoke method application in the course of local exhaust systems efficiency research. The interferometric visualization using Mach-Zehnder interferometer has been applied for the research of gaseous contaminants propagation from different sources and for a local exhaust system of these sources. The smoke visualization method has been applied for higher effects to determine efficiency of local exhaust capture. As the smoke method provides clear information of the flow picture in front of the exhaust opening, it allows to determine easily suitable operating parameters of the exhaust system. In this contribution, the attention is concentrated on a flanged exhaust hood and on a reinforced exhaust system combining exhaust and supply of air.

Příspěvek se zabývá interferometrickou vizualizací a aplikací kouřové metody při výzkumu účinnosti odsávání lokálních odsávacíhc systémů. Interferometrie s použitím Machova Zehnderova interferometru byla použita pro výzkum šíření plynných škodlivin z různých zdrojů. Kouřová metoda byla použita k posouzení účinnosti lokálního odsávání a stanovení vhodných pracovních parametrů odsávacího systému.
