摘要
介绍了一种新的流场计算数值格式——残量分布格式。它是一种多维迎风格式,适于三角形网格和四面体网格。给出了该格式的标量方程和Euler方程。算例显示:该格式能处理稳态与非稳态问题,计算精度高,有较强的捕捉激波能力,且结构紧凑,易实现编码。
A new class schemes which called residual distribution schemes was introduced in this paper. These schemes were really multidimensional upwind schemes, mainly adapted to triangular meshes (2D) and tetrahedral meshes (3D), and The formula and Euler formula of the schemes were given out. The results showed that the new schemes could deal with steady and unsteady problems with high order accuracy and the superior ability in handling nonlinear waves. It's easy for these schemes to build compact stencil and to code.
