ABSTRACT

In this study, the effects of a commercial coating and its combination with aluminum and copper microparticles were investigated on condensation heat transfer. Thus, the impacts of different coating thicknesses and different weight percentages of microparticles in coatings on the heat transfer coefficient, heat flux, contact angle, and contact angle hysteresis were investigated. The heat transfer coefficient and heat flux values of the plate with Danphobix coating that was mixed with hydrophilic aluminum microparticles with the weight percentage of 3% and coating thickness of 17 µm was increased by 2.22–2.8 times and 2.2–2.52 times, respectively, compared to the no-coating plate.

摘要

在这项研究中，研究了商业涂层及其与铝和铜微粒的组合对冷凝传热的影响。因此，研究了不同涂层厚度和涂层中不同重量百分比的微粒对传热系数、热通量、接触角和接触角滞后的影响。与重量百分比为 3%、涂层厚度为 17 µm 的亲水性铝微粒混合的 Danphobix 涂层板的传热系数和热通量值分别提高了 2.22-2.8 倍和 2.2-2.52 倍到无涂层板。
