An investigation into the interaction between an incident conical shock wave and a plane two-dimensional turbulent boundary layer is reported. The study has provided information on the interaction pattern and the surface flowfield under both attached and separated flow conditions. The existence of significant pressure gradients in the spanwise direction after the shock leads to strong crossflows. A horseshoe pattern of separation whose strength and size are reduced away from the plane of symmetry is identified. The interaction produces upstream influence, which is curved as a result of decreasing influence of the conical shock away from the plane of symmetry. Incipient separation is inferred, and it is shown that criteria for its existence are similar to other three-dimensional interactions.
