【Abstract】 In this paper, the performance of air-lift pumps is studied for water, simulating high-level-liquid-waste and 30%(ratio of volume) trialkylphosphine oxide (TRPO)-kerosene solution which are lift in the tube height of 6.2m. The relation between the used gas flow rate and the conveyed liquid flow rate is satisfied for the one-dimensional model given by Parker. Furthermore, the effect of the diameter of conveying tube, the surface stress and viscosity of the conveyed liquid on the characteristic parameters, such as slip velocity S and friction parameter, K, has been discussed in detail.更多还原
