摘要

In this paper, a numerical modeling technique is used to study the phenomenon of a jet impinging on a cylindrical surface at a constant temperature and rotating around its symmetrical axis. This phenomenon is encountered in a milling cutter cooled by a cold air jet at low temperature. The cylinder is assumed to be at a constant temperature higher than the jet's temperature. Forced convection produced by the air jet at different Reynolds numbers induces the cooling of the cylinder. For this study, we adopted a mathematical model that will be resolved by the FLUENT software based on the finite volume method. The calculation code is validated with numerical and experimental results already available in the bibliography. Our results showed that the highest value of the Nusselt number occurs near the position of H/d = 6 for all different Reynolds number configurations; meanwhile the heat transfer increases with Reynolds number and angular velocity.
