| Abstract: | This paper discusses how to use HLLC method to treat moving boundary. The explicit finite volume method based on unstructured meshes is employed to solve Eulerian equations. The impulse piston moving backward and forward is simulated to validate the moving boundary treatment. As an example, flows around a static cylinder and around a moving cylinder in a static flow field are calculated. The numerical results indicate that it is feasible to use the HLLC method to treat the moving boundary condition. |
