摘要
利民区域法对流场进行分块处理，采用分块耦会求解，数值模拟无粘跨、超音速流态下的物体绕流流动特性。数位模拟的出发方程为Euler方程，采用隐式有限体积TVD格式，给出了二维尖前、后缘翼统流和尾喷流／绕流干扰流场的计算结果。数值计算表明，该方法可以取得高清晰度的流场结构。
Characteristics of inviscous flow at transonic and supersonic speeds areinvestigated using zonal approach, and the domain decomposed and matched methods are used. The governing equations are the Euler equations, the numericalscheme is implicit finite volume TVD algorithm. Through numerical simulation,the aerodynamics for the two dimensional airfoils and interaction flow field betweensupersonic flow around the body and base jet are presented. The numerical resultsreveal that this technique is capable of providing visualizations of flow fields attaining high resolution.
