Oblique effects on the capture ability of a hood under crosswind environments - numerical method

The flow field of industrial ventilation hood induced by the combination of extract-flow and crosswind is affected by the oblique angle of the hood's set-up. The size and scope of the capture zone of toxic gases are highly influenced by the extract velocity at the hood opening and the angle of the opening to the direction of the environmental air flow. This paper presents the results of the capture efficiency calculated by numerical method.
