Аннотация

Two-phase flows of LiBr water solution in minichannels with heat exchange is experimentally investigated. Six flow patterns have been revealed: a bubble flow, plug flow, separate and wavy separate flow, dispersed flow, and flow blocking. Contrary to one-component liquids, an additional third phase may appear in desorption of salt solutions, that is, a crystal-hydrate shell on channel walls. The maximum desorption efficiency corresponded to minichannels of 3 mm in diameter and in the presence of a dispersed flow. The desorption rate depends not only on the ratio of liquid, gas, and heat flux velocities, but also on the overall interface area. The maximal interfacial evaporation surface corresponds to the dispersed flow due to the presence of a high concentration of fine-dispersed droplets. Minichannels with a high desorption rate can be effectively applied for high-temperature desorbers of thermal pumps.
