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.
Centrifugal buoyancy arising from radial temperature gradient of fluid has a great influence on the enhanced heat transfer performance of swirling flow.
由流体径向温度梯度引起的离心浮力对旋流强化传热效果有重要影响。

The results show that local heat transfer coefficients and their radial profiles are obviously influenced by the vertical length of the heat probes.
