Abstract: ALE (Arbitrary Lagrangian Eulerian) finite volume method for compressible fluid flows on moving quadrilateral meshes in two dimensional planar coordinates and axisymmetric coordinates is studied.A vertex-centered finite volume method and an HLLC numerical flux adapted to various equations of state are employed.A second order accuracy in space is achieved by using a reconstruction of primitive variables based on WENO approach.An explicit two-stage Runge-Kutta time-stepping scheme is used in discretization of time.The method offers accurate and robust solutions in capturing strong shock,contact discontinuities and material interface on arbitrarily moving grids.
