摘要：

A new model has been developed for the liquid phase flow pattern in bubble columns. This model satisfies the mass, momentum and energy balances for the gas and liquid phases. Further, it takes into account the variations in the flow pattern due to changes in the physical properties of the liquid phase. The model can be used for batch as well as continuous (co-current and counter-current) modes of operation. A satisfactory agreement is shown between model predictions and experimental observations. A simplified procedure is suggested for quick estimation of the liquid phase velocity profile. The proposed model is expected to be useful for the rational prediction of transfer coefficients for momentum, mass and heat. The prediction and measurement of the pressure drop is discussed in the companion paper.
