文摘
CFD simulations of unsteady EOF were carried out for unobstructed membrane channels.
The effect of an unsteady EOF on flux and wall shear was analysed.
Unsteady EOF shows similar or lower time-averaged permeate flux than steady EOF.
Unsteady EOF increases maximum wall shear, hence may reduce the onset of fouling.
There is a negligible change in time-averaged pressure drop with unsteady EOF.
