N2 - Measured heat transfer rates through turbulent and transitional boundary layers on an isothermal, convexly curved wall of 45 cm radius show Stanton numbers 20-50 percent below flat wall values for the same enthalpy thickness Reynolds number. Heat transfer rates recovered slowly on a flat wall downstream of the curved wall. After 60 cm, Stanton numbers were still 15-20 percent below flat wall values. Five secondary effects were studied to determine their relative importance and to guide modeling: (1) initial boundary layer thickness, (2) freestream velocity, (3) freestream acceleration, (4) unheated starting length, and (5) maturity of the boundary layer.
