大空间浮射流流动规律的数值分析及实验验证

Numerical Analysis and Experiment Verification of Buoyant Jet's Hydronamics Laws in Big Space

利用PHOENICS程序对大空间中的四环动量射流和圆环浮射流（通称四环射流或环形射流）的速度和温度分布规律进行了详细的数值分析，并用实验进行了验证，数值计算结果和实验结果基本上相同．

The detailed numerical analysis using the 3 dimensions computational fluid dynamics (CFD) software,PHOENICS, is carried out for studying the velocity and temperature distribution laws of donut momentum jets and donut buoyant jets in big space, which are verified by experiments. The resultS of the numerical analysis are considerably consistent with the results of the experiments.
