Characteristics of Heat and Mass Transfer in Condesation Process of Gas-Liquid Cross Flow

Abstract:

The condensation process of liquid-gas cross flow was mathematically modeled, and the expressions of heat and mass transfer coefficient were obtained. The characteristics of high temperature and humidity gas that flowed across an array of liquid columns were experimentally studied in various working conditions to get the heat and mass transfer coefficient. The results showed that: the heat and mass transfer coefficient of the staggered arrangement is 20~40% higher than that of the aligned arrangement; the gas turbulence near the gas-liquid interface caused by the flow of the liquid columns and that caused by the gas flow around liquid columns are the main factors that intensify the heat and mass transfer in low and high gas flow rate respectively.
