Models and calculations of the effectiveness of gas and liquid cooling in foam and film apparatuses

Abstract

An approach to determining the temperature profiles and effectiveness of gas and liquid cooling in the developed turbulent bubbling layer on trays in column apparatuses and film blocks of cooling towers has been considered. The approach is based on models of the flow structure for two-phase media. Diffusion and cell models with bulk heat and mass sources are used. The solutions of the system of equations of these models for various special cases of heat exchange in gas–liquid media on trays and in the packings of cooling towers have been given. The results of calculations and a comparison with experimental data have been demonstrated.
