三维物体表面摩阻的有限元算法

Finite-Element Algorithm for Skin Friction Calculation on 3-D Body Surface

在有限元法的框架内 ,给出一种从动量守恒方程出发计算物面摩阻的新方法 ,并用数值试验进行了验证。

In the framework of the finite element method, a new way of calculating skin friction on body surface starting from the momentum conservation equations is presented. A few examples are given to demonstrate the applicability of the new method.
