摘    要:本文提出一种高效、高分辨率求解三维复杂流场的隐式算法,并成功地用于求解高速进气道内外流场的三维、可压缩、雷诺平均Navier-Stokes方程组,获得了三个工况五种流场的三维数值解;与有关实验数据比较,结果令人满意。这种算法由Jameson-Turkel的LU分解法和张涵信NND格式的数值通量耦合而成,湍流采用BaldwinLomax模型。大量数值计算表明,该算法能捕捉到复杂的激波系,有较好的激波

关 键 词:激波捕捉  湍流模型  数值模拟  三维  进气道

Abstract:A new and efficient three-dimensional implicit hybrid scheme for Navier-Stokes equations is presented. The basic scheme is the coupling of the Jameson and Turkel's LU decompositions and Prof. ZhangHanxin's NND concept. The improved LU decompositions is applied to discretize the implicit part of the equations and Zhang's modified flux function to calculate the right hand side operators of the hybrid scheme.Numerical calculations were made of supersonic inlet flows with mixed external-internal compressions. Some of the computed results were compared with ayailable wind tunnel data.
Keywords:LU scheme  NND scheme  turbulence model  shock wave capture  numerical simulation  3-D inlet
