TLDR
In this article, different correlations used for predicting the minimum fluidization velocities of binary systems were evaluated and compared, based on the experimental data obtained from the published literature and from this work.Abstract:
The fast defluidization method was used to measure the minimum fluidization velocities of binary systems. Based on the experimental data obtained from the published literature and from this work, different correlations used for predicting the minimum fluidization velocities of binary systems were evaluated and compared.

Minimum fluidation velocity correlations in particulate systems
R. Coltters,A.L. Rivas +1 more
TL;DR: In this article, a new relationship for the prediction of minimum fluidization velocity is proposed, which is based on the dependence of the physical and chemical properties of the particle surface on the minimum fluidisation velocity, and tested using 189 measurements reported in the literature on about 90 different materials.

Measurement of size and size distribution of particles by fluidization.
TL;DR: In this article, a method of particle size distribution measurement using a fluidization curve was developed and the size distributions observed in binary and tertiary mixtures were in agreement with those by microscopic measurement.
