Abstract

The state-of-the-art tools for the evaluation of the macroscopic hydrodynamics of cocurrent upflow three-phase fluidization are critically evaluated by thoroughly interrogating the broadest fluidization database ever built. The database is compiled through worldwide conjoint initiatives as a result of a decade of compilation efforts by the groups of professors L. S. Fan (Columbus, OH), S. D. Kim (Seoul, South Korea), and G. Wild (Nancy, France) and our Laval University group. The database represents almost the whole heritage of the nonproprietary data released in the open literature in the field of gas−liquid−solid fluidization (23 000 experiments on bed porosity and liquid, gas, and solid holdups). It is dedicated to embracing wide-ranging fluids' properties, particle and vessel sizes, and operating conditions. The database contains 55 Newtonian (20 500 data), 19 non-Newtonian liquids (2500 data), 110 various particles, and 17 different column diameters and includes wall effect ratios Dc/dp and grain siz...
