The study of heat removal efficiency using a dispersed flow method

The study deals with one of the methods of effective cooling and thestabilization of the temperature of highly heat-loaded heat exchangers, based on the use of dispersed flow. The author describes the advantages of this method of heat removal and expresses the need for systematic experimental studies in order to justify its thermo-physical properties and optimization. The experimental research basis developed by the authors is described. A technique used for processing experimental data is suggested. The study shows that the temperature of the target decreases abruptly with increasing air (mixture component) flow. The author establishes a correlation of the heat transfer coefficient with the mass flow rate x of the gas content. It is shown that the increase in heat transfer practically stops at a certain value of the mass flow rate of the gas content x* ≈ 0.045. The experimental data are summarized. The author draws up a criterion equation describing the experimental data in a given range of operating parameters.
