Originální abstrakt

Visualization and measuring methods using a fog can be effectively applied to the research of ventilation and warm air heating. These methods allow visualization of airflow boundaries, and from that airflow shapes, ventilation efficiency, etc. can be deduced. In the course of research of air jet from ventilation outlets, it is possible to use visual recordings to evaluate mainly the length of the marginal zone and the expansion angle in the main zone, which in turn determines the outlet constant for example. Analysis of non-isothermal jets easily enables evaluation of jet axis position, while dynamic visual recordings permit the qualitative evaluation of jet stability, jet direction, etc. This paper outlines various examples of visual recordings whose results can be extrapolated towards further quantitative analysis of flows in ventilated and heated spaces.
