摘要

提出了二元混合物在垂直圆管中降膜蒸发的传热传质耦合数学模型及其相应的数值解法 .模型考虑了液膜内传质对传热的影响 .计算表明传质对传热有明显影响

忽略传质的影响对预测膜平均传热系数会带来较大误差 .

Abstract

A model of falling film evaporation of binary mixture on the inside wall of a vertical tube and corresponding numerical Solution are presented.Heat and mass transfer are closely conjugated in this model.The effects of mass transfer on heat transfer are taken into account.It is found that mass transfer significantly affects heat transfer.Neglecting the effects of mass transfer in heat transfer will bring great error for predicting heat transfer coefficient.
