Abstract
The purposes of this study were to evaluate the effects of moving objects on the rate of transport of indoor air pollutants and to propose a method of controlling contamination in an indoor environment. First, the rate of transport of air pollutants by a swinging door was calculated using computational fluid dynamics (CFD) with a moving mesh technique. The rate of transport of pollutants between an air contaminated room and corridor as a result of a swinging door was calculated to verify a CFD model. Then, the effects of moving objects on the rate of transport of indoor air pollutants were evaluated in various instances and several ventilation plans were devised for a smoking room. Results showed that leakage rates increased with an increasing velocity of door opening and human movement. Moreover, installation of a sliding door and maintaining negative room pressure help to decrease leak of indoor air pollutants from a smoking room.
