Capture efficiency of a local exhaust system, e.g. a kitchen hood, sho
uld include only contaminants being direct captured. In this study bas
ic concepts of local exhaust capture efficiency are given, based on th
e idea of an imaginary control box. A validated numerical model is use
d for estimation of the capture efficiency. An experimental technique
is introduced for field studies taking into account knowledge of flow
patterns of air and contaminants obtained from smoke testing and conta
minant concentrations.
