Added mass effects are incorporated into a formulation of the equations of change for fluidization (the particle bed model) using the very simple procedure proposed recently by Wallis (IMA Workshop Proceedings, in press, 1989) for two-phase flow. Added mass is shown to significantly affect the behaviour of liquid fluidized beds of relatively low density particles. Quantitative predictions of this effect on the velocity of dynamic waves are found to improve agreement with experimental measurements.
