TWO PHASE FLOW EXPERIMENTAL DETECTION METHOD AND CFD MODELS – A REVIEW

open access: yesJournal of Engineering and Sustainable Development, 2020
Liquid two-phase flow has been studied widely by many authors. Two phase flow exist in petroleum industries, nuclear power generation and chemical plants. In the present study a review on two phase flow such as oil/water was discussed, also the patterns

Geometric displacement volume and flow in the phase of a two-phase hydraulic converter

open access: yesResearch in Agricultural Engineering, 2007
The paper researches the possibilities to replace the parallel flow hydraulic mechanisms in agricultural machinery with hydraulic units with fluid alternating flow as they provide more efficient operation due to their output alternating motion.

A study of CO2 two-phase flow in a near horizontal pipe

open access: yesJournal of Pipeline Science and Engineering, 2023
In this article, the observations from two different experimental studies on CO2 two-phase flow regimes in a near horizontal pipe are analysed. These experiments show significant bubble entrainment in a stratified flow, and the bubble entrainment in ...

Flooding and Flow Reversal in Annular Two-Phase Flows [PDF]

open access: yesSIAM Journal on Applied Mathematics, 1992
Summary: A two-fluid model for annular two-phase flow is presented, which incorporates realistic phase interaction terms corresponding to turbulence in the gas phase, interphase pressure differences, and profile effects (nonuniform velocity profiles); this model avoids the conundrum of illposedness associated with the simplest averaged model.

Flow Regimes and Transitions for Two-Phase Flow of R152a During Condensation in a Circular Minichannel

open access: yesFrontiers in Energy Research, 2021
Two-phase flow regimes were experimentally investigated during the entire condensation process of refrigerant R152a in a circular glass minichannel. The inner and outer diameters of the test minichannel were 0.75 and 1.50 mm.

Design and Construction of a Two-Phase Flow Homogenizer Loop for Volume Fraction Measurement in Solid-Liquid as Well as Liquid-Liquid Mixtures by γ-Ray Attenuation Technique [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2016
Multiphase flow metering, has been one of the most important issues in oil/gas industry, since the early 80s. Oil-water two-phase flow, shows off specially in flow meters that work based on separation of oil-water-gas three-phase flow into liquid (oil ...
