| 摘 要： | 采用ＬＵ隐式方法求解了有限体积法离散的完全Ｎ－Ｓ方程，数值模拟了三维高超声速喷流干扰流场。计算中采用了Ｊａｍｅｓｏｎ的当地极值递减（ＬＥＤ）格式和Ｂａｌｄｗｉｎ－Ｌｏｍａｘ代数湍流模型，与实验结果相比较，数值方法对附体流动计算较准确，对分离区附近流场计算有一定误差。

| Abstract: | A time dependent, implicit,finite volume,lower
upper(LU) numerical method was developed to solve the three dimensional Navier Stokes
equation. The numerical procedure uses Roe's flux difference splitting and Jameson's LED
scheme for the connective terms and central difference scheme for viscous terms. Baldwin
Lomax algebraic turbulence model was used to enclose the governing equations. Numerical
solutions of hypersonic jet interaction flowfield with attack angle are obtained, and the
numerical results were compared with experimental data. |
