Investigating binary mixtures fluidized using a porous plate

The aim of this study was to give a simple correlation to give a first-approximation value for the minimum fluidizing velocity of a binary system. In contrast to many previous studies into predicting the minimum fluidizing velocity of a binary system fluidized using a porous plate distributor, this investigation proposes a purely empirical correlation for estimating the values of u_M u_S and u_FF based on plotting Archimedes' number against Reynolds' number using experimental data from a wide range of sources. This produced correlations based on the general form Ar = A Re^B, which were shown to compare well with actual results.
