N2 - The effects of streamwise convex curvature, recovery, and free-stream turbulence intensity on the turbulent transport of heat and momentum in a mature turbulent boundary layer is investigated. A special three-wire hot-wire probe developed for this purpose is described. Two cases with free-stream turbulence levels of 0. 68% and 2. 0%, taken in the same facility with moderate strength of curvature, PARTIAL /R equals 0. 03, are compared. Profiles of u prime v prime , t prime , u prime t prime , and v prime t prime are dramatically reduced within the curve, with asymptotic profiles being achieved quickly for the low T. I. case. Recovery occurs rapidly, with the profiles often overshooting flat-wall upstream values.
