Large Eddy Simulation of Shock/Boundary Layer Interaction

Abstract

Since results obtained with the RANS approach are not satisfactory, it appears natural to assess the capacity of LES to simulate such interaction. From a numerical point of view, it necessitates the use of schemes designed to minimize the numerical dissipation in shock-free region of the flow since it was demonstrated in 1 that the numerical dissipation of high-order shock-capturing scheme can exceed the subgrid-scale dissipation. To satisfy this requirement, we use a strategy 2 built on the mixing of the characteristic based filters 3 and a sensor 4 able to distinguish a turbulent fluctuation from a shock. To validate this approach, the case of the interaction of an oblique shock with a boundary layer developing on a plane plate was chosen since it has been extensively studied experimentally at IRPHE 6 7.
