This study explores the characteristics of twin-screw pumps when operated in turbine, ie,
reverse mode as an alternative to traditional control valves in piping systems for recovering …

This paper presents analysis of a novel multiphase scroll pump to transport gas–liquid two-
phase mixtures, in which each compression chamber has a flank clearance which forms a …

This study is focused on the development and validation of an analytical model to predict the
performance characteristics of multiphase flow twin-screw pump for wide range of operating …

The performance of twin-screw pumps that are widely used in industry hinges upon a
number of factors. In this research, a systematic approach is presented, encompassing the …

Accurate prediction of the flow rate curve of a stroke for reciprocating multiphase pumps
often encounters several challenges in practice, including process nonlinearity, dynamical …

This paper presents a model of the heat transfer processes in the casing and rotors of a twin-
screw multiphase pump. The model was developed to study the influence of temperature …

Accurate description of the quick and nonlinear change of the discharge flow rate in
reciprocating multiphase pumps is important but difficult. To ensure the reliability of …

In this paper, it is presented a methodology for an exergetic comparison between two
artificial lift systems: a gas lift and a twin-screw multiphase pump system. A software (Hysys …

The performance of a multistage electrical submersible twin-screw pump (ESTSP) was
evaluated under different operating conditions. The effect of working fluid, differential …

Unsteady three-dimensional flow simulations on a twin-screw pump are performed for an
assessment of the radial, circumferential, and flank gap flow effect on the pump …
