求解跨音速流动时物面边界条件的处理方法

Approximate Treatment of the Solid Boundary Conditions in the Calculation of Transonic Flow

用时间相关法求解跨音速流动时,合理而有效地处理物面边界条件是十分重要的。本文提出几种物面边界条件的处理方法,并对几个例子进行了数值试验,对其结果进行了讨论。

In the computation of transonic flow by the time marching method, it is very important to use the reasonable and efficient approximate treatment of the solid boundary conditions. In the present paper several methods are proposed to treat the solid boundary conditions, numerical tests are performed for some samples, and the results are discussed.
