【 摘 要 】

The effect of velocity, channel's width, particle size and concentration on particles' deposition efficiency were simulated and analyzed by Fluent. The results show those particles' deposition efficiency increases with the increase of air velocity. When the air velocity is greater than zero point five meters per second, the deposition efficiency begins to decrease slightly. The deposition efficiency of the particles increases with the increase of the airflow channel width when the airflow channel size is reasonable. The particles' deposition efficiency increases with the increase of the concentration. When the particle's concentration reaches 250μg/m3, the deposition efficiency no longer changes.
