Prediction of Minimum Fluidization Velocity in Two-Phase and Three-Phase Fluidized Beds: Air/Newtonian and Non-Newtonian Liquids

The present experimental data on minimum fluidization velocity for two-phase and three-phase fluidized beds, involving 459 measurements were used for the analysis. Apart from this, 70 literature data points from different published sources, using 11 different liquids and 11 different particles have been used for the development of minimum fluidization velocity correlation. The developed correlation for the prediction of the minimum fluidization velocity for two-phase and three-phase fluidized beds was found to be satisfactory for the Newtonian and non-Newtonian systems with a wide range of variables covered in the present investigation.
