摘要

摘要本文介绍了毛细管多孔涂层上水平薄液层沸腾时的传热实验研究。利用增材三维打印技术和选择性激光烧结技术制造了不锈钢涂层样品。在涂层上观察到了沸腾曲线的反转，与未涂层表面相比，温差减少了五倍。经过 350 小时的测试周期后，发生沸腾曲线反转的热通量速率下降了 7 倍。

Inversion of the Boiling Curve on Microstructured Porous Coatings

Abstract

The paper presents an experimental study of heat transfer during boiling in a thin horizontal layer of liquid on a capillary-porous coating. A sample of a stainless steel coating was manufactured using additive 3D printing technology with selective laser sintering. An inversion of the boiling curve was observed on the coating, which led to a fivefold decrease in temperature difference compared to an uncoated surface. After 350 h of the test cycle, the heat flux rate at which the boiling curve inversion occurred decreased by a factor of 7.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
