对超声波强化单相对流传热、过冷沸腾传热、饱和沸腾传热的机理与研究进展进行综述,指出今后应着重研究的方向。在单相对流传热和过冷沸腾传热阶段,超声波能使传热系数得到提高,尤其单相对流传热阶段更为显著;在饱和沸腾传热阶段,超声波虽然能对传热产生一定的影响而效果并不明显,但可能会提高临界热流密度。
The mechanisms and research pro- gress in enhancement of single-phase convection heat transfer, subcooled boiling heat transfer and saturated boiling heat transfer by ultrasound are reviewed, and the direction that should be focused on research in the future is pointed out. The heat transfer coefficient can be enhanced by ultrasound in single-phase convection and subcooled boiling heat transfer stages, especially in single-phase convection heat transfer stage. In satu- rated boiling heat transfer stage, the ultrasound has a certain impact on heat transfer but the effect is not ob- vious, and it is possible to increase the critical heat flux .
