| 摘 要： | 对三维对流项在四面体单元上建立了一种各结点控制体相一致的一种质量加权迎风方案，它既保留了质量加权方案对大的Ｐｅｃｌｅｔ数及非结构式几何域的适用性，又简化了计算机程序的实现过程。

| Abstract: | A new mass-weighted(MAW)upwind interpolation scheme,the control-volume finite-element method,is adopted for three dimensional convection term based on tetrahedral element,and its subcontrol volumes and surfaces on each element are symmetrical.This feature not only guarantees the positive coefficients in the discretization equation,but also is easy to be fulfilled in the computer program.The scheme has been applied successfully to some three dimensional convection-diffusion problems and some three dimensional viscous,incompressible fluid flow problems. |
