Technique of dynamical mesh

The moving human (MH) influences the airflow and contaminant distribution, this paper use the commerce software FLUENT6.2 to simulate the influences of the MH to the airflow and TVOCs distribution in both mixing ventilation and placement ventilation. In a three-dimension ventilation room, a pollutant source (TVOCs) was located on the floor and a flesh in a certain zone moving was assumed,  and the unsteady, k-ξ turbulent model be used, According to the simulation results, we studied the influence of MH in the indoor air quality in both mixing ventilation and displacement ventilation.
