Hypersonic Boundary Layer Tripping to Turbulence on a Conical Body
A low Reynolds number hypersonic flow boundary layer tripping on a conical body is studied. The experiments are performed in a conventional shock tunnel at conditions providing flight realistic combination of Reynolds number and Mach number. It is observed that it is difficult to trip such a flow even with diamond trip heights as much as five times the local boundary layer thickness. Heat flux measurements over the cone indicate that though trip causes local disturbance in the flow field, the boundary layer seems to relaminarize toward the end of the cone.
