The mass transfer equation was introduced into heat transfer model of falling film evaporation. The radial velocity, mass diffusion coefficient and variation of film thickness were taken into account.
In this thesis, the heat transmission coefficient and exit density of two-effect evaporation experimental facility are investigated.
本文以两效蒸发实验装置的传热系数和出口浓度在线检测系统为研究对象。

The influence factors of the heat transfer performance and the formula of the heat transfer coefficient on the evaporation side in the umbrella-plate have been obtained.
