Impact of mans movement on air contamination control in crucial medical rooms（1）：a review

The impact of unsteady aerodynamic wake of mans movement on contaminant transportation should be taken into account in the air contamination control of crucial medical rooms, and most previous studies regard the occupant as static object, which resulted in the contaminant distribution in hospital being rather different from the actual situation. Summaries the research status, particularity and CFD method of the dynamic simulation, and points out that the CFD simulation of contaminant distribution in the crucial medical rooms should be reoriented from static method to dynamic method.
