Abstract

The results of an experimental investigation on heat transfer and critical heat flux during surface cooling with a dispersed flow of deeply subcooled liquid are presented. The study was carried out using a pressure nozzle with a mass flow rate of water of 24.2 g/s. A record critical heat flux of 13.2 MW/m² was achieved in these experiments. The findings indicate that the onset of boiling within the liquid film formed on the impact surface during spraying leads to a notable reduction in the temperature non-uniformity across the heater.

过冷水喷雾冷却过程中的传热机制和临界热流密度

本文给出了深度过冷液体分散流表面冷却过程中传热和临界热流密度的实验研究结果。实验采用压力喷嘴，水的质量流量为24.2 g/s。在这些实验中，临界热流密度达到了13.2 MW/m2。研究结果表明，喷射过程中在冲击表面形成的液膜内沸腾的开始导致加热器温度不均匀性的显著降低。

期刊介绍： The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
