Abstract: Transonic flow over an oscillating airfoil has been computed by solving the Euler equations. A finite volume scheme is used to spatially discretize the integral form of the Euler equations for a moving domain, and a symmetric TVD scheme is presented to construct dissipative terms. The method may robustly and accurately capture moving shock waves in flowfield. Furthermore, the computing technique allows a very neat extension to the treatment of arbitrary movement and deformation of the mesh.
