Bed expansion in liquid–solid two-phase fluidized beds with Newtonian and non-Newtonian fluids over the wide range of Reynolds numbers

Minimum Fluidization Velocity and Expansion Behavior of Spherical Particle Beds Fluidized with Inelastic and Viscoelastic Fluids

“…From Figure 9a, it is observed that the velocity−voidage relationship for the VIF is showing same trend as for the NF in the case of flow behavior index, n ≃ 1. However, with the increase in non-Newtonian flow behavior, the voidage in the bed increases for the same u/u t similar to the results reported by Miura et al 60 With a decrease in the value of n, the shear-thinning effects are enhanced which decreases the circulation of particles and enhances the nonuniformity of particles along the height of the bed. 19 To quantify the effect of the flow behavior index, many models are reported in the literature to predict z as a function of n and d p /D.…”

Numerical Prediction of Hydrodynamic Characteristics of Wet Particles and Power-Law Fluids in a Fluidized Bed Using the Dynamic Restitution Coefficient

“…Model Validation. Figure 3 presents the comparison between the liquid volume fraction in the bed and the experimental findings by Miura et al 38 under different superficial liquid velocities. The predicted results for both dry and wet particles are well consistent with the experimental values at various liquid velocities.…”

Bed expansion of binary mixtures of irregular particles in solid–liquid fluidization: Experimental, empirical correlation, and GA‐ANN modelling

“…The bed voidage was expressed as follows: The mean holdup of solid particles in bed was calculated based on the dry particle's weight, M s , and the measured bed height at fluidization. [ 37 ] The variation in bed voidage, , for the Newtonian liquid with liquid velocity for a different particle diameter of the binary system is depicted in Figure 4. It can be concluded from Figure 4, that increased in magnitude with the increase in liquid velocity.…”
