摘要:
基于Delaunay非结构网格生成方法和局部阵面推进重新生成网格的方法,应用边界边剖分与合并技术,对二维含自由表面流动中运动边界网格的生成方法进行了研究,改善了局部网格重新生成过程中的网格质量;对激波诱导变形水液滴在高速气流作用下的受力情况做了数值模拟。结果表明:该文在处理二维自由表面的动边界问题中采用的方法是可行的。
Abstract:
Unstructured mesh generation technique is investigated for two dimensional flow with free-surface.Delaunay method and local advancing front approaches are used to cope with element deformation around moving boundaries.Boundary edge splitting and merging approach are proposed to optimize the distribution of boundary points.Qualities of local regenerated elements increase.Numerical examples of flow around deformed droplet induced by shock indicate the validity and robustness of the developed methods.
