Abstract

This article presents an experimental and numerical study of the heat transfers in rotating disk with an impinging jet. The disk is cooled using the impingement of an eccentric air jet. Local Nusselt numbers are experimentally determined on the entire surface the rotating disk using infrared thermography. A numerical study is carried out with ANSYS-Fluent computation code and based on ak- RNG numerical turbulence model. the obtained result was compared in term convective heat transfer with numerical and experimental data for rotational Reynolds number between Rew=2.38×105 and 5.44 × ×105. A good agreement between the two approaches has been reached. This agreement validates a numerical model for calculating the convective heat transfer in a rotating disk.
