Mechanics of fluidization

TL;DR: In this article, a mathematical model was developed to describe the minimum fluidization velocity behavior of a cocurrent, gas-liquid-solid fluidized bed with cylindrical hydrotreating catalysts under conditions of high gas holdup.

TL;DR: A critical review of the proppant settling in hydraulic fractures, with an emphasis on the experimental studies published in the past several decades, can be found in this article , where six factors are identified: wall retardation, fluid rheology, non-uniformity, surface wettability and fracture complexity.

TL;DR: A kinetic theory based two phase flow model for plasma andred blood cells (RBCs) is shown to explain the Fahraeus–Lindqvist effect, the migration of red blood cells from the wall to the center in narrow tubes.

TL;DR: In this article, an energy minimization multi-scale (EMMS) approach was applied to a fluidized bed operating at the ranges between the bubbling regime and packed bed, and simulation results showed very good agreement with the Krishna [20] bed expansion experimental data, while the modeling using homogeneous drag force diverged considerably from the experimental data.
