摘要
提出了气液相际传质的三膜模型．该模型认为，气液相际传质有三个阻力膜层：气膜、液膜和界面阻力膜．本文对模型中的参数进行了分析，并且进行了实验验证．结果表明，三膜模型能较好地反映两相间传质的规律．
The three film model was proposed for gas liquid interphase mass trasfer based on the concept of three resistance films——gas film,liquid film and interfacial resistance film,which exist in the gas liquid mass trasfer process,and the parameters of the new model have been analysed.The experimental results show that the model proposed has a higher accuracy than the two film model to describe the processes of gas liquid two phase mass trasfer.
