生物安全实验室气流组织效果的数值模拟研究
Numerical simulation study on air distribution effects in biosafety laboratories
摘要：
对上送上排和上送下排气流组织形式下生物安全实验室内的污染物浓度场和气流速度场进行了数值模拟，结果表明上送下排在室内污染物排除效果上明显优于上送上排。将数值模拟结果与模型实验结果进行了对比，二者基本一致。

Abstract：
Numerically simulates the concentration field of contamination and the velocity field of airflow in biosafety laboratories applying up-supply and opposite up-exhaust mode and up-supply and opposite down-exhaust mode. The results show that the latter mode is much better than the former one in contamination eliminating. Compares the numerical simulation results with those from a model experiment, and finds that they are in good agreement.
