Abstract

Eulerian approach is developed in order to determine the flow pattern and the concentration field in dense solid-liquid suspension in an industrial vessel. These numerical simulations are a very practical aid to understand and design the solid-liquid processes. The knowledge of solid distribution is useful for numerous processes, including crystallization, where vessel performance is closely linked to the solid phase distribution. The calculations are performed using the FLUENT commercial package. The crystallizer studied is used for alumina production. The predicted solid distributions in this crystallizer are compared with experimental solid distribution for several rotational speeds and mean concentrations. The agreement is remarkable. The behaviour of this dense solid-liquid system is studied.
