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。 Based on the adaptive Cartesian grid, the virtual unit method was used to deal with the boundary of immersion. A finite volume format realization mode was developed and the two - dimensional viscous flow was numerically simulated. Compared with the traditional finite difference method, the method developed in this paper has the advantages of fast execution, easy to obtain the conservation and so on. Finally, the validity of the proposed algorithm is verified by the calculation of some standard and multi-object flow fields.
