摘要/Abstract

摘要： 用隐式有限体积法求解三维N－S方程数值研究超燃冲压发动机三维平行、垂直喷流干扰流场。计算中采用了具有当地极值递减（LED）性质的JST和SLIP中心差分格式。为了减缓计算网格数很多时对计算机内存的压力以及提高计算效率，运用了通量守恒的分区计算方法。

Abstract: Implicit finite-volume method has been used to solve three-dimensional N-S equations to study three-dimensional parallel and vertical jet interaction flow field numerically. The central difference schemes JST and SLIP that satisfy LED principle are used. To relax the demand on computer memory and to raise the efficiency when the computational grid number is very large, the flux conservation multizone methods are applied.
