An experimental and analytical study was made on the effect of transverse convex surface curvature on the fluid flow and heat transfer in the turbulent boundary layer for incompressible axial flows along a circular cylinder. The analysis is based on a modified turbulence model of Hornby, Mistry and Barrow with variable von Karman`s constants, K{sub i}. The deviation of flow and heat transfer properties from those of flat plates is demonstrated. The agreement between the analyses and the experimental results for skin friction and heat transfer rate is good. The study demonstrated that, for a given condition, both the friction coefficient and Nusselt number increase with decreasing value of the cylinder radius and that their values are always greater than those for the flow over a flat plate.
