Abstract

The impact of shock waves on supersonic cooling films is studied using large-eddy simulations (LES). A laminar cooling film is injected through a slot at a Mach number M​a i =1.8 into a fully turbulent boundary layer at a freestream Mach number M​a ∞ =2.44. The cooling film is disturbed by oblique shock waves at deflection angles of 5∘ and 8∘ at two downstream positions of the slot. At shock impingement close to the slot, i.e., within the potential-core region, at a flow deflection of 5∘, a cooling effectiveness decrease of 33% occurs downstream of the separation bubble compared to a configuration without shock impingement. If the same shock impinges further downstream upon the boundary-layer region, the decrease is only 17%. The stronger 8∘ shock wave at the further downstream impingement position leads to a maximum decrease of 33%. The current report presents a concise version of Konopka etal. (4th European conference for aerospace sciences, 2011).
