Numerical simulation of heat transfer analysis of a horizontal rotating cylinder in water using open foam

Abstract

The present work concern with the comprehensive study of heat transfer from a horizontal heated cylinder rotating in water coefficient. Above this critical value, the heat transfer coefficient is just a function of Earlier work done by Researcher has shown the importance of the critical Reynolds number in determining the heat transfer Reynolds and Prandtl number while Grashof number has negligible effect in the heat transfer coefficient. The work has shown the variation of Nusselt number with different angular position on the cylinder circumference with peak value of local Nusselt number at the bottom and lowest at the top for a stationary cylinder, and the variation tend to shift on the graph as Reynold number is increased with lowest Nu number going more down and highest Nu number going up. This variation tends to flatten out with increase in Reynold number.
