数值研究报告了由管道突然膨胀产生的分离流和重新连接流中的流动和传热。在这项研究中，主要关注的是基于壁函数的湍流近壁模型的开发。还采用有效的数值方法来计算高速流动。将计算结果与之前获得的实验数据进行比较。一般来说，采用现有的近壁模型可以获得较好的结果，其中三层模型优于两层模型。
A numerical study is reported of flow and heat transfer in the separated and reattached flows created by an abrupt pipe expansion. In the study attention has been given primarily to the development of turbulence near-wall models based on the wall function. An efficient numerical method is also employed for the computation of high-velocity flows. The computed results are compared with experimental data obtained earlier. Generally, better results are obtained by employing the present near-wall models, and among them the three-layer model is superior to the two-layer one.
