湿空气掠过竖直壁面的凝结换热研究
Research of humid air condensation heat transfer across the vertical wall
摘要
Abstract
Numerical methods were used to study the heat and mass transfer characteristics of humid air across a vertical cold wall, based on the analysis of the humid air condensation, to discuss equations applied for condensation mass flux of humid air and the assumption of neglecting thin condense on heat transfer. Discussions were made on the effects of temperature, velocity and concentration of humid air on the interface velocity normal to cold wall and condensation mass flux of humid air. The practicable conditions for these humid air condensation equations were obtained. Results indicated that the temperature of plate surface was the decisive factor of advective mass flux and the advective mass transfer could reach 5％ of the total mass transfer for wall temperature of 310 K. The assumption of neglecting thin condense was proved to produce error of less than 1％ during present study.关键词
