摘要
医院关键科室内应考虑人体活动引起的动态尾流对空气中污染物扩散的影响,通常假设人体静态的模拟方法并不能反映真实情况。对人体动态模拟的研究现状和特殊性及其CFD模拟方法进行了介绍,提出对医院关键科室内污染物扩散的模拟应逐渐从稳态模拟向动态模拟转变。
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.
