Hydrodynamic interactions and mass transfer in solid-liquid systems – a particle

Many chemical engineering processes rely on mass transfer between a solids phase and a liquid phase. Agitation and fluidization of dense solid-liquid suspensions are common ways of enhancing transfer rates. Slip velocities between the phases contribute to the transport of species towards and away from the solid-liquid interfaces. We present detailed simulations of flow dynamics and mass transfer in dense suspensions with explicit resolution of the solid-liquid interfaces. Challenges we face relate to the high Schmidt numbers usually associated with liquids which ask for dedicated numerical methods for sufficient resolution of the (fine) mass-transfer boundary  s, and to handling interactions between non-spherical particles in dense suspensions.
