Mixing in segregated, binary-solid liquid-fluidized beds

A simple model for predicting solid concentration distribution in binary‐solid liquid fluidized beds

“…and . Compared to the fitted values used in the literature, the calculated low solid concentration (close to zero) in the present work realistically accounts for the presence of the small amount of foreign particles in a mono‐component zone …”

Simulation of continuous boric acid slurry reactors in series by microfluid and macrofluid models

“…Eq. (19) is the same equation as Eq. (6a), except t is the real time in a batch reactor whereas t PFR is the mean residence time in PFR.…”

“…For a given state of macromixing (i.e., a given RTD), these two extremes of micromixing will give the upper and lower limits on conversion in a non-ideal reactor [16][17][18]. Macrofluid (segregation) and microfluid models have different applications in investigating the behavior of the liquid-solid mixtures [19][20][21][22]. On the basis of a reactor model, the experimental data has been used to evaluate the degree of segregation within the reaction mixture [23].…”

CFD-accelerated bioreactor optimization: reducing the hydrodynamic parameter space

“…The hydrodynamics of fluidized-bed reactors have been investigated experimentally 28,29 and with simulations, 30–34 but membrane bioreactor studies of microbial activity have largely focused on experimental testing. 35,36 These studies do not track particle dynamics at high volume fraction (low porosity), but instead focus on macroscopic behavior such as fluidization stability and expansion.…”
