A numerical study of fluid flow and heat transfer in circular tubes roughened with an internal circumferential rib is presented. Laminar flow with constant wall temperature is considered while the influence of heat conduction in the tube wall is also incorporated in the analysis. It was found that heat transfer is affected by the ratio of thermal conductivity of the wall to that of the fluid. Significant increase in heat transfer is achieved only for high Prandtl number fluids in the ribbed tube. The higher pressure drop in a ribbed tube should also be considered in a cost-effective design. There are no experimental results available in the open literature to compare with the present computations.
