隔离病房气流分布模拟与评价
Simulation and evaluation of air distribution for isolation wards
摘要：
采用CFD数值模拟的方法，利用相关评价指标对四种不同气流分布方式进行了比较分析，认为天花板顶送异侧下排是较为理想的气流分布方式。建立了实体模型，对这种气流分布方式的排污效果进行了实验测试，结果令人满意。

Abstract：
Based on the CFD simulation, analyses and compares four air distribution modes using relevant evaluating indexes, and concludes that the topsupplying and opposite downexhausting air distribution is an optimal mode for isolation wards. With a fullscale model, tests the contamination exclusion effect of the air distribution mode and the result is satisfactory.
