Abstract

In the present paper, the impingement of air jet on a heated flat plate subjected to a periodic oscillation is numerically and experimentally investigated. The motivation of the present research is the desire to enhance the heat transfer characteristics during the cooling process of a heated flat plate which can be found in many relevance industrial applications. In order to improve the heat transfer characteristics, a novel idea is utilized, where a periodical oscillation movement in form of sine wave produced from a Scotch yoke mechanism is applied to the heated flat plate. The obtained numerical results showed a good agreement with the performed experimental measurements. Moreover, an increase of the Nusselt number is obtained from an oscillated plate in comparison with that obtained from a fixed plate. This reveals the enhancement of the heat transfer characteristics of a heated flat plate as a result of the applied periodic oscillation movement.
