Large eddy simulations were made of transonic flow over a two-dimensional bump where shock wave/turbulent boundary layer interaction takes place. Different flow conditions were investigated to find conditions for large scale shock movement. The innermost part of the shock was found to be moving for sufficiently strong shocks. None of the cases display large scale movement of the whole shock. (c) 2010 Elsevier Inc. All rights reserved.
