Kurzfassung
Based on a given solution method for inviscid gas dynamic equations, a guideline is presented to compute the three-dimensional unsteady flow around vibrating airfoils or turbomachinery bladings. First of all, the basic numerical scheme (flux vector splitting) and its application in curvilinear coordinates are presented. Afterwards, space-time discretization of the transformed equations is discussed, where special attention is focused on implicit time integration. One special section deals with the implementation of wall and far-filled boundary conditions, while another one studies the generation of timedependent grids under different conditions. Finally, numerical examples for vibrating airfoils and turbomachinery bladings are presented and discussed.
