| 摘要: |
| 从沸腾换热特性及其影响因素、沸腾汽泡行为和沸腾换热关联式等方面综述了添加表面活性剂的沸腾换热强化研究现状。现有研究指出界面吸附、分子结构、粘度、溶解特性等因素对表面活性剂溶液沸腾换热的作用机制与表面活性剂种类和溶液浓度密切相关，但是蒸汽携带活性剂、非离子活性剂浊点、加热方法、系统压力、参数耦合等因素对表面活性剂溶液沸腾换热的影响规律的研究还需深入开展。在沸腾汽泡行为方面，表面活性剂溶液沸腾汽泡行为与水存在较大差异且与活性剂种类有关，表面活性剂溶液沸腾汽泡行为的理论研究还需加强。此外，现有文献建立的表面活性剂溶液沸腾换热模型及关联式存在验证所用的实验数据较少、模型参数难以确定等不足。最后，在总结现有研究进展的基础上对表面活性剂溶液沸腾换热的后续研究工作提出了建议。 |

| Abstract: |
| A detailed review on boiling heat transfer enhancement by surfactant additives are presented in this paper to show the characteristics, bubble behaviors and correlations of boiling heat transfer of surfactant solutions. The results point out that the effects of interfacial adsorption, molecular structures, viscosity and soluble characteristics on boiling heat transfer of surfactant solutions are related to the surfactant ionic natures and concentrations of surfactant solutions in present literature. However, the influences of steam carrying, cloud point, heating method, boiling pressure and parameter coupling on boiling heat transfer of surfactant solutions are not well understood at present. In the aspect of bubble behaviors, the existing literatures show that the bubble behaviors of surfactant solutions are quite different from that of water and more emphasis should be put on the theoretical study. In addition, the boiling heat transfer correlations of surfactant solutions in the open papers exist the deficiency of less experimental data for verification and model parameters difficult to be determined. At last, some aspects that need to be investigated further and some new ideas in these fields are presented. |
