摘　　要：对声空化及其产生的物理效应的研究工作作了较为全面的描述,对国内外利用声空化实现强化传热的研究工作动态与进展作了全面系统的论述与分析,并结合对声空化现象的理论与实验的研究成果,概括了以往研究的主要结论.目前,其研究工作主要以实验为主,并在实验的基础上揭示声空化强化传热的物理机制.由于声空化及其效应的复杂性,声空化强化传热物理机制的认识、数学模型及准则关联式的建立是进一步研究工作仍将面临的问题.Research on acoustic cavitation and its physical effects is described and the development and progress achieved in the research on enhancement of heat transfer with acoustic cavitation at home and abroad are discussed and analyzed. The main conclusion obtained in the past is summarized in combination with achievement of mechanism and experiments of acoustic cavitation. At present, the study on acoustic cavitation enhancement of heat transfer is further performed by experimental investigation in terms of the physical mechanism. Because of the complexity of acoustic cavitation and its effects, not only the physical mechanism should be revealed, but also the enhancement mathematical model and correlative equation must be established.
