Study on the separation in the shock wave/boundary layer interaction induced by a curved fin

The effect of an isentropic compression wave fan on shock wave/turbulent boundary layer interaction induced by a curved fin is studied the nanoparticle-based planar laser scattering method, oil flow and numerical method. consists two parts: A surface generating ensuring focuses into swept wave. flowfield compared with three-dimensional separation same deflection angle. results show that can compress turbulent without separation, while focused drives whole to separate. flat plate beside mainly rolled vortex. adjusts zone be quasi-conical, suggesting quasi-conical nature in which interacts part prevent secondary changing attachment process. Based focus point fan, equivalent apex proposed. area intensity vortex are nearly linear as those flowfield. However, larger. growth caused slower than fin.
