The influences of aerator aperture size and aeration rate on the gas hold-up, liquid circulation velocity, wall shear stress and turbulence intensity in a novel airlift ceramic membrane filtration equipment containing a 19-channel ceramic membrane was investigated by the CFD simulation. Further, the VOF model was adopted to simulate the flow state of the gas-liquid two-phase fluid and the mean error between experiment date and simulation date was 5%—10%. The results demonstrated that the gas hold-up increas...
