... and 70 bara. This campaign was conducted as part of a project aimed at improving the physical models in LedaFlow for near-vertical pipes, and was divided into several parts. The first part was dedicated to liquid loading in wells, and was published in BHRG 2016 [1]. The current paper describes the second...

... model. The latter one, also called phenomenological model, requires the use of closure relations to solve the transfer of mass, momentum and energy between the phases, in the respective conservation equations, so that integral flow parameters such as liquid holdup (or void fraction) and pressure...

The experimentally and theoretically investigated twin screw pumps are displacement pumps, which work with two axially parallel and inversely...
