Intensification of foam technology by the energy of the electrohydrothermal power field. Part 3. Investigation of the processes of heat and mass transfer in the foam system under the influence of EHTPF

Abstract

As a result of thermal expansion in the foam mass of the gas phase, which acts as a sealing component in a closed volume, excessive internal pressure is generated and fields of pressure, temperature, and moisture content are formed. Particular flows of liquid arising from these fields are directed from the center to the perforated walls of the form with a distance beyond it. In EHTPF, there are three partial flows of moisture that make up a single flow in the mass. Thus, self-compaction is accompanied by heat and mass transfer processes. At low temperatures, moisture moves in the material in the form of a liquid, and at high temperatures, in the form of vapor. The density of the total moisture flow can be represented as the sum of the densities of private flows. An analytical study of the mechanism of heat and mass transfer flows allows one to analyze the behavior of the foam mass during heatpower treatment and to choose the best conditions for it.
