Numerical study of fluid flow and heat transfer over a rotating disk at arbitary angle of inclination in laminar flow

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.This article presents an experimental and numerical study of heat transfer from a rotating disk in still air for a large range of angle of inclination and laminar boundary layer over the rotating disk. The Nusselt number over the rotating disk was measured and compared with the numerical results data obtained from numerical study. The goal of the present research is to develop a semi empirical correlation in the familiar classical form for a circular rotational disk for any arbitrary angle of inclination, velocity of rotation and various size over a wide range of the Reynolds numbers. Our results show that the local Nusselt number has not a strong relation with angle of inclination.
