A mechanistic model based on the drift line created by a spherical bubble passing through a liquid is developed to predict the gas holdup in gas-liquid-solid three-phase fluidized beds containing small or low density particles. In the model development, the drift line calculated from stream function for the three-dimensional case is used to predict the mean liquid rise path in the bubble street. The gas holdup can be estimated from the mean bubble rise velocity obtained by the sum of the following : the single bubble rise velocity, the mean liquid velocity calculated from the mean liquid rise path, the gas velocity in the bubble street, and the liquid velocity. Agreement between the calculated and measured values of εg is fairly good using the correction factor. Also agreement of the calculated values of εg with the measurements in the bubble column is good using a constant correction factor of around 0.7.
