Minimum fluidization velocity for binary mixture of sand particles using pseudoplastic liquids

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

“…From Figure a, it is also observed that for the same particle diameter, the bed gets fluidized earlier in the case of inelastic fluid, and the fluidization takes place more early at higher concentrations of inelastic fluids. Similar results have been reported by Let et al, Miura and Kawase, and Maiti et al This earlier fluidization is attributed to an increase in the pseudoplasticity and viscosity of fluid whose combined effect has been modeled in the literature using Archimedes number Ar defined as …”

“…From Figure 2a, it is also observed that for the same particle diameter, the bed gets fluidized earlier in the case of inelastic fluid, and the fluidization takes place more early at higher concentrations of inelastic fluids. Similar results have been reported by Let et al, 20 Miura and Kawase, 52 and Maiti et al 53 This earlier fluidization is attributed to an increase in the pseudoplasticity and viscosity of fluid whose combined effect has been modeled in the literature using Archimedes number Ar defined as Therefore, a comparison of observed inelastic fluid experimental values with the values predicted by models/ equations of Brea et al, 17 Kumar and Upadhyay, 39 Kawase and Ulbrecht, 24 Machačet al, 40 Ciceŕon et al, 25 and Aghajani et al 54 is presented in Figure 2b. From the figure, it is observed that most of the experimental data lie in the range of ±25% of parity with MRQE of 18.42%, which depicts that the available expressions can be used safely in case of Newtonian and inelastic power law fluids.…”

“…In recent years, the study of spherical beds fluidized by non-NFs has gained momentum due to its applications in the production of microbial mass in fermenters, extraction of metals from leached pulps by ion exchange, food and polymer processing, biotechnological applications, − biochemical reactors with a bioagent attacher, catalytic polymerization in a hydroxidation process, and fluidized bed electrodes . However, in comparison to NFs, little information is available for both non-Newtonian inelastic fluids and viscoelastic fluids (VEFs).…”

Hydrodynamics Behavior of Ternary Biomass Mixtures with Silica Sand in Fluidized Beds: Experiment and Artificial Neural Network Model Development

“…In addition to U mf , the pressure drop is considered an important parameter for operating and scaling up a fluidized bed reactor, especially for biomass fluidization where greater heterogeneity in particle size, shape, and density exists. − Table provides a comprehensive overview of the literature reviews. It is evident that previous studies have primarily focused on investigating bed materials comprising a single biomass type or combinations of only one biomass type with inert particles, such as silica sand.…”
