隔离病房开门过程中气流的数值研究
Numerical study of air distribution in door opening process of isolation wards
摘要：
研究了利用动网格技术解决动态病房开门数值模型中边界发生移动的问题。模拟了开门过程病房内外压差的变化，门附近的流场状况，以及进出门气流的变化状态，探讨了开门对污染物扩散的影响。模拟结果和已有试验结果的对照说明利用动网格技术模拟该动态过程流场是可行的。

Abstract：
With the dynamic grid method, studies the boundary moving problem of the numerical model for isolation wards. Simulates the changes of pressure difference, velocity field and the air flow in the door opening process, and discusses the influence to the contamination dispersion. The comparison of simulation results and existing experimental results shows that it is feasible to apply the dynamic grid method to this model.
