Visualization of the Evolution of a Single Vapor Bubble During Boiling of a Subcooled Liquid: Experience in Automating the Processing of High-Speed Video Recording Results

Subcooled liquid boiling makes it possible to remove extremely high heat flux densities (tens, and under certain conditions even hundreds of MW/m2). This method is used for cooling rocket nozzles, in metallurgy, thermonuclear power special installations (cooling beam targets), pulsed magnetohydrodynamic (MHD) installations. However, the calculations this process are based on purely empirical correlations. The lack experimental data characteristics bubbles (size evolution, life time, formation frequency) hinders development mathematical models calculation methods. paper presents a program developed Python 3.10 environment automated processing high-speed video recordings evolution single bubble during subcooled liquid. Comparison frame processing, carried out «manually» with help program, showed fairly agreement between results. significantly reduce time spent material include larger array analysis.
