Based on the CFD simulation, analyses and compares four air distribution modes using relevant evaluating indexes, and concludes that the top-supplying and opposite down-exhausting air distribution is an optimal mode 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。
