Unit-Reynolds-number effects on boundary-layer transition

The effects of increasing Reynolds number on the boundary-layer transition of turbulent flows is investigated. Planar and conical boundary-layer transition are compared at aMach number of eight to obtain the unit-Reynolds number effects. Hot-wire anemometry experiments are also conducted at the same Mach number. Results showthat the cone transitin data obtained produces a unit-Reynolds-number that is steeper than the wind-tunnel planar slope.
