Unstructured grid system is suitable for flows with complex boundary geometry's. As for the problem with moving boundary walls, the grid system is also changing and deforming with time. In this paper, a new moving-grid finite volume method on unstructured grid system is presented and developed for unsteady compressible flows. To assure geometric conservation laws on moving grid system, a control volume on the space-time unified domain is adopted for estimating numerical flux. The method is implicit and is solved iteratively at every time step in order to assure both the geometric conservation laws and numerical accuracy. The method is described for two-dimensional flows and validated using simple test problems. Application to a piston problem and a gun tunnel problem has shown a promising feature of the method.
