Abstract

Experimental data on the study of boiling of superfluid helium (helium II) on a cylindrical heater inside a porous structure are considered. Based on an analysis of video recordings, the heat and mass transfer modes characterized by significant modification of the shape of the phase interface are classified. The values of heat fluxes and heater temperatures are presented, and the degree of nonequilibrium of the corresponding transfer processes is assessed.

多孔结构内圆柱形加热器上氦气 II 的沸腾模式

摘要考察了在多孔结构内的圆柱形加热器上研究超流体氦（氦Ⅱ）沸腾的实验数据。根据对视频记录的分析，对以相界面形状的显著改变为特征的传热和传质模式进行了分类。文中给出了热通量和加热器温度值，并评估了相应传质过程的非平衡程度。

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.
