| Abstract: | We give discretization for fluid system in integral form with arbitrary moving velocity on unstructured meshes, where re-mapping step in ALE method to interpolate flow variables between old mesh and new one can be avoided. We give three kinds of velocity for different part of computational domain, and apply the scheme to pitching Naca0012 airfoil with moving boundary. It shows that the scheme is efficient and accurate. |
