摘要

摘要 报告了在管壳式蒸发器中水平管束下流动的液膜在蒸发和沸腾时的传热情况。该管束包括经过微弧氧化(MAO)处理的硬铝管,其传热特性是测试的主题。绝对压力为 3 巴的制冷剂 R21 被用作工作液体。通过管束泵送的热水被用作热载体。与普通管子相比,经过 MAO 处理的测试管子获得的沸腾曲线显示出相当大的传热性能提升;但是,由于微弧氧化涂层的多孔结构而产生的滞后现象也显露出来。在操作传热设备时应考虑到这些现象。

Hysteresis Phenomena at Boiling in Liquid Film Flowing down the Tubes with Microarc Oxidation Coating

A study of heat transfer at evaporation and boiling in liquid film flowing down the horizontal tube bundle in tube-and-shell evaporator is reported. This bundle includes duralumin tubes with micro-arc oxidizing (MAO) treatment, which heat transfer characteristics are the subject of conducted tests. Refrigerant R21 at the pressure of \(\sim\)3 bar of absolute pressure is used as working liquid. Hot water pumped through bundle tubes used as a heat carrier. The boiling curves obtained for the tested tubes with MAO treatment showed considerable heat transfer enhancement in comparison with plain tube; however, hysteresis phenomena due to a porous structure of micro-arc oxidizing coatings are revealed. These phenomena should be taken into account at operating heat transfer equipment.

期刊介绍: Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
