用HLLC方法处理运动边界

MOVING BOUNDARY PROBLEMS USING HLLC METHOD

  • 摘要: 针对含有运动边界非结构网格点的显式有限体积方法,研究了如何使用HLLC方法处理运动边界条件,计算了活塞拉伸、压缩问题,并和解析解进行了比较. 作为应用示例,比较了静止圆柱绕流和静止流场中运动圆柱的绕流情形. 结果表明:应用HLLC方法处理运动边界是可行的.

     

    Abstract: This paper discusseshow to use HLLC method to treat moving boundary. The explicit finite volume method based onunstructured meshes is employed to solve Eulerian equations. Theimpulse piston moving backward and forward is simulated tovalidate the moving boundary treatment. As an example, flows around a staticcylinder and around a moving cylinder in a static flow field arecalculated. The numerical results indicate that it is feasible to use theHLLC method to treat the moving boundary condition.
