The Gas-Perturbed Liquid Model, previously applied to predict minimum liquid fluidization velocities for coarse-particle gas-liquid-particle systems, is extended to predict the minimum superficial liquid velocity for particle transpotr, U_(et). Experiments were performed with air, water and three types of particles, with U_g up to 5.9 m/s. The present model predicts our glass bead results and literature results well. For steel shot, all equations underpredict U_(et), due to cluster formation. A dimensionally homogeneous empirical equation fits all available data.
