Abstract
Impinging jet is very useful for heat transfer and mass transfer enhancement. Historical research process on the impinging jet heat transfer is described systematically. The present paper is composed of two stages. In the first stage, the heat transfer characteristics of impinging jet are described for the heat transfer movement of a single circular impinging jet, an inclined jet and an impinging jet with an oscillated surface. In the second stage, a systematic structure of an impingin jet and a heat transfer mechanism are explained corresponding to the turbulent structure at the stagnant region, turbulent heat flux and three-dimensional vorticity.
