Abstract
An analysis was developed for the flow resistance of the nanoporous filtration membrane with conical pores for a liquid-particle separation, based on
the nanoscale flow model. The calculation results show that there exists the optimum cone angle of the conical pore which gives the lowest flow
resistance and thus the highest flux of the membrane; This optimum cone angle of the conical pore depends on the radius of the small opening of the
conical pore, the passing liquid-pore wall interaction and the membrane thickness. The equations were regressed out for calculating this optimum
cone angle respectively for weak, medium and strong liquid-pore wall interactions. For the optimum cone angle of the conical pore, the
dimensionless minimum flow resistance of the membrane was calculated and it is only dependent on the radius of the small opening of the conical
pore and the passing liquid-pore wall interaction.
