摘　　要：研究沸腾换热过程是安全、高效地利用能源的基础.简要评述了沸腾换热(池内沸腾、流动沸腾、临界热流密度和纳米流体沸腾换热)的研究进展;详细论述了采用分形理论和方法研究沸腾换热分析解的理论和方法;指出了采用分形理论和方法有可能解决其它尚未解决的有关沸腾换热的若干课题和方向.Study on boiling heat transfer has attracted more and more attentions due to its safe and efficient utilization of energy sources. In this paper, an overview of recent advances in the area of boiling heat transfer is presented, and basic fractal geometry theory is introduced. Several fractal models for the nucleate pool boiling, subcooled flow boiling, CHF and nanofluids boiling heat transfer are reviewed, summarized and discussed Finally, comments and suggestions are made with respect to further development in this new frontier.
