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.
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.
