TLDR
In this paper, a new steady state air-lifts model is proposed to predict the pressure gradient in the riser by a combination of specific models describing slug and churn flow, based on the available literature on two-phase flow.About:

Air-lift pumps characteristics under two-phase flow conditions
TL;DR: In this article, an air-lift pump was designed and tested for nine submergence ratios and three risers of different lengths with different air injection pressures, and the results showed that the pump capacity and efficiency are functions of the air mass flow rate, submergence ratio and riser pipe length.

A Study of Flow Patterns for Gas/Liquid Flow in Small Diameter Tubes
TL;DR: In this article, a flow pattern specific method for void fraction prediction has been applied and its predictions are in good agreement with the measured mean void fraction, and a modification to the bubble-to-slug flow transition of Taitel et al. (1980) gives improved predictions in narrow passages.

Investigation of vertical slug flow with advanced two-phase flow instrumentation
TL;DR: In this paper, the authors used an electromagnetic flowmeter and an impedance void-meter in an air-water two-phase experimental loop to measure the liquid velocity and the impedance of vertical slug flow.

Experimental constraints on the outgassing dynamics of basaltic magmas
TL;DR: In this article, the authors investigated the dynamics of separated two-phase flow of basaltic magmas in cylindrical conduits and calculated vesicularity and pressure gradient for a range of gas superficial velocities (volume flow rates/pipe area, 10−2-102 m/s).

Modelling flow pattern transitions for steady upward gas-liquid flow in vertical tubes
TL;DR: In this paper, the authors developed models for predicting flow pattern transitions during steady gas-liquid flow in vertical tubes based on physical mechanisms suggested for each transition, incorporating the effect of fluid properties and pipe size.
