A ghost cell method on finite volume adaptive Cartesian grids and its applications

  • 摘要: 基于自适应笛卡尔网格,结合虚拟单元方法处理浸入边界,发展了一种有限体积格式实现模式,数值模拟了二维无粘可压缩流动。本文发展的方法相对于传统的有限差分方法具有执行效率快,易于获得守恒性等优点。最后,利用一些标准算例和多物体流场的计算问题验证了算法的有效性。

     

    Abstract: A finite volume scheme with the ghost cell method based on adaptive Cartesian grids is presented for two dimensional compressible flow problems.The implementation procedure shows that the present method is more efficient and easier conservation preserving than finite difference schemes.Finally,some numerical examples and multi-body flow problems are given to illustrate the efficient of the method.
