Liquid-to-solid mass transfer in a microfluidized bed consisting of monosized, spherical particles in a Newtonian liquid has been studied numerically. The simulations fully resolve the laminar, near-creeping flow of the solid-liquid suspension. In addition, passive scalar concentrations in the liquid at high Schmidt number (Sc up to 10(4)) have been determined. Solids volume fractions are in the range 0.18-0.27. The concentration boundary conditions are such that the scalar can be thought of as being adsorbed on the solid particle surfaces. The simulations quantify the overall adsorption performance of the fluidized bed, and they provide insights in local variations (per particle and over individual particle surfaces) of mass transfer rates.
