GS15 Development of Ventilation System for Nonsmokers Used in Hall without Partition : Verification experiment with actual scale

Abstract

We often perceive odors of smoking at seats for non-smokers of cafes and restaurants. A new ventilation system was developed by using the knowledge that neither flow separation nor backward flow could occur in case of increasing velocity distribution near walls by using 1/10 models. In this paper, the effects of the system was examined by using an actual scale model, and it was confirmed that the system could remove smoke promptly, and that unsteady flow prevented smoke from staying in the backflow behind columns.
