An experimental investigation of the effects of convex curvature and free-stream turbulence on momentum and heat transfer in a boundary layer undergoing natural transition was performed. The test selection was designed for providing a two-dimensional boundary layer flow on a uniformly heated curved surface. The unique feature of the test wall was its flexibility to be bent to various radii of curvature, R. Three cases of R equals infinity , 180 cm, and 90 cm, are presented, each with two free-stream turbulence intensity levels, 0. 68% and 2%. Mean velocity and temperature profiles and local Stanton number data were taken in a heated flow and streamwise Reynolds normal stress profiles were taken in an isothermal flow. The results of this study increase the data base for development of transition prediction models which can be used in gas turbine blade design.
