采用混合长度模型 ,用共轭数值计算的方法研究了高位垂直进气转静系旋转盘、腔内的流动与换热 ,得到了盘、腔内的流场、温度场、转盘表面的平均努赛尔特数 ,并与实验结果进行了比较。计算结果显示 :扩展的混合长度模型对高位垂直进气转静系旋转盘流动与换热的计算是可行的。
The mixing length model was used to study the flow and heat transfer in the high vertical inlet rotating static system rotating disk with the method of conjugate numerical calculation. The flow field, temperature field and the mean surface of the disk were obtained. The number of Celtic, and compared with the experimental results. The calculation results show that the extended mixing length model is feasible for the calculation of the flow and heat transfer of rotating turret with high vertical inlet.
