TLDR
In this article, the effects of design parameters viz. mass flow rate of air, immersion ratio, diameter of rising main etc. on the performance of air lift pump are presented.Abstract:
Airlift pumps are finding increasing use where pump reliability and low maintenance are required, where corrosive, abrasive, or radioactive fluids must be handled and when a compressor is readily available. The objective of the present study is to evaluate the performance of a pump under predetermined operating conditions and to optimize the related parameters The effects of design parameters viz. mass flow rate of air, immersion ratio, diameter of rising main etc. on the performance of airlift pump are presented. The larger diameter of rising main is found to be suitable for high flow rate of water. The injecting device used in the system has considerable effect on the performance of the pump. The paper is focused on the general mathematical expression to determine the effective diameter of nozzle applicable to air lift pump installations in the diameter range of 25.4 mm < d < 101.6 mm. The various types of flows are visualized in the rising main of a pump and the corresponding airlift pump performance is analyzed. It is observed that the slug flow is more predominant for improving the performance of the pump.read more

The effect of air injection system on airlift pump performance
TL;DR: In this paper, a novel design of an air injection system for an airlift pump was designed and tested, and the results showed that both the airflow rate and the submergence ratio have a significant effect on the capacity and performance of the pump.

Effect of Suction Pipe Diameter and Submergence Ratio on Air Lift Pumping Rate
TL;DR: In this article, an air lift pump system was setup to study the effect of the suction pipe diameter and submergence ratio on the liquid (water) pumping rate, and the experimental results show good compatibility with the model suggested by Stenning and Martin for the performance of an air-lift pump.

Entropy analysis of buoyancy driven gas–liquid two-phase flow: Analytical and experimental approaches
TL;DR: In this paper, an experimental entropy analysis of an air-lift pump is presented, and the entropy generation of a pump plays a substantial role in its performance, i.e., gas-wall and water-wall frictions, phase interactions, and losses due to relative velocities.
