The formation of a closed vapor film during boiling of helium II on a cylindrical heater inside the porous structure

Abstract

The results of experimental studies superfluid helium (He-II) film boiling are presented. Experimental studies of the He-II boiling on the surfaces of the cylindrical heaters in a bulk of He-II and under constrained conditions are described. Visualization of helium-II film boiling was first performed when observed from the end of a cylindrical heater. The scheme of the experimental facility, work cell and heater are given. The data in the form of files with visualization obtained from the experiments allow us to determine the outlines and the characteristic sizes of the films formed during boiling for different initial conditions.
