Frequency of formation of vapor bubbles in a two-layer medium of magnetic and nonmagnetic liquid

Abstract

A method for measuring the frequency of formation of vapor bubbles formation during the boiling of opaque liquids using a two-layer system (with opaque and transparent media) is proposed and implemented. An experimental device has been developed, and experiments have been carried out to determine the frequency of formation of vapor bubbles during the boiling of opaque liquids. The frequency of the formation of the vapor bubbles is measured in the boiling of a two-layer medium of magnetic and nonmagnetic liquids on a horizontal surface with a point heat source in a uniform external magnetic field. It has been found that with an increase in a uniform constant magnetic field, the frequency of the formation of vapor bubbles in the boiling of a two-layer medium of magnetic and nonmagnetic liquids on an unlimited horizontal plate decreases, whereas the temperature of the heat-releasing surface, at which the vaporization process begins, increases for the samples of magnetic liquids with a high magnetic phase content
