Investigation of Intensive Cooling of High-Temperature Bodies in Binary Water–Isopropanol Mixture

Abstract

Abstract The available experimental data on metal-body quenching in subcooled water indicate the presence of extremely intense cooling at the surface temperatures exceeding attainable limiting temperature of the liquid. At present, there is not only a theoretical description but also well-founded qualitative description of the mechanism that makes it possible to remove such heat fluxes in film boiling mode. In experiments on cooling in cryo-liquids, fluorocarbon, ethanol, and isopropanol, such a regime does not occur even at extremely high subcooling. Thus, it seems expedient to perform experiments on the cooling of high-temperature samples in a binary water–isopropanol mixture. For the first time, the boundary concentration of the isopropyl alcohol in the mixture with intensive cooling that occurs upon film boiling is determined.
