本文研究了喷雾水滴与高温物体表面之间的传热。试验测定了锥形喷嘴的冷态特性和水滴与高温表面的传热系数,讨论了影响传热系数因素,并得出了h∝W关系式。 This article studies the heat transfer between the spray droplets and the surface of a hot object. The cold state characteristics of conical nozzles and the heat transfer coefficient between water droplets and high temperature surface were measured. The factors influencing the heat transfer coefficient were discussed and the relation of hαW was obtained.
