为了阐明自增湿流体过冷池沸腾的基本传热特性和强化换热，以稀庚醇水溶液为过冷池沸腾工质，进行了一系列的沸腾实验。在实验中，采用了使用水平加热丝的沸腾系统。研究了不同过冷度(1℃、5℃、10℃、15℃)和不同浓度(0、0.01wt%、0.05wt%、0.1wt%庚醇水溶液)的SRWF沸腾性能。实验结果表明，过冷温度越高，换热性能越好，能有效防止干涸现象。0.1wt%庚醇水溶液具有较好的表面张力和浓度梯度，具有最佳的临界热流密度，有利于提高干燥极限。用高速摄像机记录了加热钢丝的成核沸腾过程。此外，从沸腾现象可以看出，SRWF的沸腾气泡更小、更多，这有利于在小型热器件中的应用。
To clarify the fundamental heat transfer characteristic and heat transfer enhancement of subcooled pool boiling with self-rewetting fluid (SRWF), using dilute heptanol aqueous solution as SRWF, a serial boiling experiments have been carried out. During the experiments, a boiling system using a horizontal heated wire was employed. The boiling performance of SRWF with different subcooling (1 °C, 5 °C, 10 °C, 15 °C) and different concentrations (0, 0.01 wt%, 0.05 wt%, 0.1 wt% heptanol aqueous solution) have been demonstrated in this paper. The experimental results show that, the higher subcooled temperature leads to the better heat transfer performance, and it can effectively prevent the dry out phenomenon. Due to better surface tension and concentration gradient, the 0.1 wt% heptanol aqueous solution shows the best critical heat flux, which is beneficial for increasing the dry out limit. With a high speed video camera, the nucleation boiling process on the heated wire has been recorded. Furthermore, it is found from the boiling phenomenon that, the boiling bubbles of SRWF are visualized to be much smaller and more, which is conducive to the application in small thermal devices.
