Experimental Investigation on Drying of Forest Biomass Particles in a Mechanically Stirred Fluidized Bed

“…For the U mf velocity prediction, a new correlation is proposed based on a procedure reported in [18]. The initial correlation studied fits well with experimental data in the range of small particles.…”

Gaseous fluidization of short fibers and powders, influence of temperature and pressure

“…However, the Ergün equation assumes the knowledge of the bed porosity at the minimum fluidization velocity (ε mf ) and the sphericity of the particles (ψ s ), two characteristics that are sometimes difficult to evaluate. Many studies [32][33][34][35][36] propose correlation coefficients which avoid the assumptions made on ε mf and ψ s , but the multiplicity of these coefficients, specific to the nature of the fluidized bed, make the correlations poorly reliable. Moreover, it is important to note that the proposed correlations are only valid in the case of laminar and inertial flow.…”
