In this paper, experimental data and numerical results of heat transfer from a heated rotating disk in still air are presented over a large range of inclination angles and a dimensionless correlation isdeveloped for forced, natural and mixed convection. The measured Nusselt number over the rotatingdisk is compared with the numerical results. The goal of the present research is to develop a semi empirical correlation in the familiar classical form for a rotating disk at any arbitrary inclination angle over a wide range of rotational Reynolds numbers. The results show that the local Nusselt number does not change dramatically with inclination angle
