| 摘 要： | 本文以弯管内分离流场为例，根据分离区与未分离的湍流动能差别较大的特点，提出了在分离区和未分离区采用不同的湍流模型来模拟流动的湍流效应，利用Ｎ－Ｓ方程进行了数值模拟，结果表明：利用这一方法，可以加速迭代的收敛，节省机时。

| Abstract: | Based on the experimental result of turbulent kinetic energy,it is suggested in this paper that different turbulence models in different regions were ernployed to account for the effect of turbulence of the flows.Numerical test for 2-D separated flow in bend duct have been conducted, and the result shows that computation with this method gives reasonably good agreement with the experiment. |
