In this paper, the influence of performance parameters of airlift pumps, such as: pipe diameter, submergence ratio, flow regimes and pipe length, has been numerically investigated, and the design criteria of the airlift pump have been optimized. The results are compared with the experimental data and show that the present model is in good agreement with other models. The model is used to carry out parametric studies and to optimize the maximum efficiency under various operating conditions. The results show that there is an optimum diameter for a given set of pump operating conditions. The results are discussed for different submergence ratios and tube lengths, in order to increase the efficiency of an airlift pump.
