Abstract
A further understanding is developed of the physics of three-dimensional shock-wave/turbulent boundary-layer interactions produced by asymmetric double-fin geometries. A numerical method is employed to reproduce the mean flow of an experimental test matrix of six configurations composed of all combinations of 7-, 11-, and 15-deg fins, yielding interactions of various degrees of asymmetry and strength. The nature of asymmetric interactions is discussed with particular emphasis on the case where the two sharp fins have angles of 7 and 15 deg, respectively. The flowfield can be described in terms of a vortical structure impinging on a side wall and becoming aligned in a direction parallel to it. Details of the shock pattern and vorticity field are correlated with the streamline structure and assimilated within the framework developed in previous work for symmetric interactions. The changes occurring with increasing interaction strength in the total pressure map and vorticity field are elucidated
