The effects of electrolytic pool boiling with and without the application of charged surfactants on heat transfer performance were experimentally investigated. The experiments were conducted at the saturated state under atmospheric pressure. This is the first study of the heat transfer mechanism in pool boiling using electrolysis with charged surfactants on copper tubes. The results indicate that heat transfer performance is not proportional to the applied electrolytic current. An optimal current was obtained for the enhancement of the heat transfer coefficient during electrolytic boiling. Supported by high-speed images, an analysis of bubble behaviors under different conditions was conducted. Compared with when water was used as the working fluid without the application of an electric field, the use of charged surfactants in electrolytic boiling with a current of 3 mA resulted in a 1.68 times higher heat transfer coefficient due to the number of bubble nucleation sites and the bubble departure frequency. Furthermore, the circumferential surface temperature distributions during boiling under different experimental conditions were elucidated by the analysis of bubble dynamics.

实验研究了使用和不使用带电表面活性剂时电解池沸腾对传热性能的影响。实验在大气压饱和状态下进行。这是在铜管上使用带电表面活性剂电解对池沸腾传热机制的首次研究。结果表明传热性能与施加的电解电流不成正比。获得了用于提高电解沸腾过程中传热系数的最佳电流。在高速图像的支持下，对不同条件下的气泡行为进行了分析。与在不施加电场的情况下使用水作为工作流体时相比，由于气泡成核点的数量和气泡离开频率，在电流为 3 mA 的电解沸腾中使用带电表面活性剂导致传热系数高 1.68 倍。此外，通过气泡动力学分析阐明了不同实验条件下沸腾过程中的圆周表面温度分布。
