UNSTEADY EULER SOLUTIONS FOR ARBITRARILY MOVING BODIES AND BOUNDARIES

A methodology for the computation of unsteady Euler flows in configura tions with moving boundaries is presented. The procedure is composed o f a moving and adaptive grid management algorithm and a Lagrangian-Eul erian flow solver. The domain discretization is handled via unstructur ed triangular grids. The now scheme uses a generalized version of Roe' s approximate Riemann solver, which takes into account the mesh moveme nt while satisfying in an intrinsic way the geometric conservation law s. Grid-flow coupling is obtained through error estimation. The method ology is applied to various flow problems showing moving shock waves a nd moving geometries.
