| 摘 要： | 该文根据ＷａｎｇＪ．Ｃ．Ｔ．的二阶ＴＶＤ有限体积法求解守恒型Ｅｕｌｅｒ方程，对原文中的数值格式进行了部分修改。计算网格单元是非均匀的任意四边形。文中计算了楔形风洞中的斜激波反射问题和无粘喷流近场流动结构问题。数值计算结果表明，该文方法具有激波分辨率高、计算稳定、伪振荡小等优点。同时该文方法可以处理任意复杂边界的二维及轴对称流动问题的计算，也可以将该文的有限体积法思想推广到三维具有复杂边界的流动的计

| Abstract: | In this paper,a TVD finite volume scheme with 2nd accuracy is adopted tosolve Euler equations in conservation laws. Parts of the numerical scheme are modified.The cells are nonuniform quadrilateral.The problem of oblique shock reflection andinviscid jet flow are calculated.The numerical results show that the present scheme hashigh resolution of shock wave,nonoscillation and high efficiency to process two-dimensional and axisymmetric flow problems with complex configurations, This finite volumescheme can also be applied to the calculations of three-dimensional flow with complexconfigurations. |
