Numerical experiments by computational fluid dynamics (CFD) simulation were done toinvestigate air distribution in displacement ventilated rooms with a moving person, which affects thermal stratification of indoor air required for controlling and maintaining good air quality and high efficient ventilation performance. The distributions of indoor air and ventilation effectiveness obtained by the simulation were compared with the experiments using a full-scale room model. Simulation results showed there was a significant difference of thermal stratification and ventilation performance among the cases with the different object moving speed.
