“…It is also evident from table C-1 that the discharge and efficiency of pump for 63.5 mm diameter rising main is greater compared to 38.1 mm diameter rising main. The results obtained are in conformity with the results given by Stenning and Martin (1968) who has challenged the results of Pickert (1931) that narrow diameter pipe are better from an efficiency point of view. …”

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.

“…Then based on momentum balance equation, the flux rate of liquid is determined [6]. Kassab et al utilize the Stenning and Martin equation, see Equation (21), combining with momentum method to solve the flux rates of solid and liquid directly from gas flux rate [19].…”

Airlifting technology utilized in deep-sea mining (DSM) industry was proposed in the 70s of last century, which was triggered by the discovery of vast amounts of mineral resources on the seabed. The objective of this paper is to assess the technological feasibility and profitability analyses in terms of solid production rate, energy consumption per tonnage of mineral, and profitability per tonnage of mineral. The effects of submergence ratio, pipe diameter, particle diameter, mining depth, and gas flux rate are investigated. The analysis is based on a numerical calculation performed in a Matlab environment. The research reported in this paper can assist to select an optimal transport plan for DSM projects depending on its solid production rate, energy consumption, and profitability.

“…The slip factor s is equal to the ratio of the air superficial velocity V a to the water superficial velocity V w , taking values between 1.5 and 2 (Stenning and Martin 1968). The friction factor f is calculated by considering only the liquid phase of volumetric discharge Q w þ Q a .…”

“…Nemet (1961) proposed a similar relation, indicating also that the frictional pressure drop increases with void fraction. Parker (1980), based on the theoretical model for airlift pumps of Stenning and Martin (1968), determined the total pressure drop between the entrance and the outlet of the riser tube of airlift pumps, for which the pressure drop is a linear function of the length.…”

The pressure behaviour in riser tubes of a short airlift pump was investigated for various submergence ratios, air discharges and riser tube lengths. Two high-frequency response pressure transducers were placed at various positions along the riser tube. The analysis of the recorded pressure signals gave the mean local pressure at specified vertical positions for various submergence ratios, air discharges and riser tube lengths. The experimental data show a non-linear pressure behaviour near the exit of the air ejector due to the increased friction losses in this region. The pressure behaviour for increasing air discharge at a position along the riser tube is related to the corresponding two-phase flow pattern in the riser tube. The pressure distributions along the riser tube for various submergence ratios were compared with the predictions of the Stenning-Martin model.
