Abstract: A mathematical model describing the two dimensional liquid phase flow on a tray is presented, in which the k-ε model of turbulent flow was adopted with consideration of the rising vapor as a resisting force. The calculated results show that the theoretical prediction is in agreement with the experimental measurement.
