典型环境流条件下温排水变态率数值模拟研究

Environmental Conditions Typical Cooling Water Flow Rate of Numerical Simulation of Abnormal

采用雷诺应力模型,对典型环境流条件下不同几何变态率的温排水出流流场、温度场进行了数值模拟研究,得到了不同工况下流场与温度场的分布情况,与物理模型试验结果基本一致。同时也发现,在模型变态率ε≤3情况下,不同变态率模型的流场与温度场基本特性大致相同,说明小变态率模型基本可以反映取排水口近水区流场与温度场的基本特性,这与前人的研究成果是一致的。

In this paper,Reynolds stress model,the typical environmental conditions of different flow rate of cooling water geometric metamorphosis of the flow field,temperature field numerical simulation,obtained under different conditions of flow field and temperature field distribution,and physical model test results basically the same.Also found in the model metamorphosis rate ε≤3 cases,different models of abnormal rate of flow and temperature field roughly the same basic characteristics,indicating a small basic model can reflect the rate of metamorphosis take outlet near water flow-field and temperature field of the basic feature,this is consistent with studies of previous.
