Abstract

Computational fluid dynamics is used to investigate the behaviour of the fluid flow between two rotating filter disks. The fluid is assumed to be Newtonian, incompressible, non-fouling and isothermal. The k-ε model is used to describe turbulent flow in a pressurised housing specially surrounding the rotating membrane. The axial gap between two rotating disk was found to has significant effect on the shear stress over the filter disk. Increasing the rotation speed of the filters decreases the permeate flux. The back pressure phenomenon can be a voided by a careful choice of the operating conditions.
