| Abstract: | Jet impinging is an available method for strengthen heat transfer.The impingement parameter influences directly the heat transfer characteristics.This paper studied the heat transfer characteristics of the high velocity and temperature jet impinging with the numerical simulation methods,especially the effects of the impinging distance between the nozzle and the impingement surfaces and the angle between the axis of the nozzle and the impingement surfaces.The study results has offered the significant reference for the heat transfer characteristics of the high velocity and temperature jet impinging in theoretic research and the application of engineering. |
