Modelling of Three Phase System with Non-Newtonian Liquid Using Computational Fluid Dynamics Model

A 2 dimensional numerical simulation was used to describe the flow behaviour and circulation pattern of three phase system inside an isothermal slurry bubble column using a finite volume technique. The three phase system consists of; air as the gas phase, non-Newtonian solution of poly acryl amid (...
