Abstract Various methods have been proposed to improve the boiling heat transfer coefficient. In this study, subcooled pool boiling is performed using a thin brass plate that is partly attached close to a heating surface. The plate can be vibrated because boiling bubbles grow and collapse in the gap between the plate and heating surface. The natural vibration frequency of the plate is investigated based on its material properties and fixing conditions. The wall temperature of the heating surface decreases by 5 K when the natural frequency of the plate matches the frequency of the growth and collapse of the boiling bubbles. The results show that the vibration material can improve the boiling heat transfer coefficient.

自激振动增强沸腾传热

摘要 为了提高沸腾传热系数，人们提出了多种方法。在这项研究中，过冷池沸腾是使用部分靠近加热表面的薄黄铜板进行的。由于沸腾气泡在板和受热面之间的间隙中生长和破裂，板可以振动。根据板的材料特性和固定条件研究板的固有振动频率。当板的固有频率与沸腾气泡的生长和破裂频率相匹配时，受热面壁温降低5 K。结果表明，振动材料可以提高沸腾传热系数。
