给出了提高二维Euler方程定常解质量的非结构网格自适应方法和模拟结果。流场算法为结点型有限体积法和Lax－Wendroff格式。网格用阵面推进法生成，生成初始网格时使用均匀的直角坐标背景网格。自适应采用再生网格，但不使用背景网格，而以流场解的梯度信息来构造再生时所需要的网格尺度参数源项。计算了无粘微波在固壁上的反射、NACA0012翼型跨声速统流和马赫数为3的前台阶统流，自适应效果较好．
The unstructured grid adaptive method and simulation results for improving the steady solution of two-dimensional Euler equations are given. The flow field algorithm is the knot-point finite volume method and the Lax-Wendroff format. The mesh is generated using a facelift method that uses a uniform rectangular coordinate background mesh when generating the initial mesh. The regeneration grid is adaptively used, but the background grid is not used. The gradient information of the flow field solution is used to construct the source term of the grid scale parameter required for regeneration. The reflection of non-stick microwave on the solid wall was calculated. The NACA0012 airfoil transonic flow and Mach-flow front flow of 3 were calculated, and the adaptive effect was better.
