Experimental Study and Prediction Modelling for Slippage Effect of Gas-Liquid Two-Phase Nozzle Flow

open access: yesShiyou jixie, 2022
In order to accurately predict the dynamic parameters of gas-liquid two-phase throttling production of wellbore,a physical simulation test device for gas-liquid two-phase nozzle flow was built.With this device,liquid holdups at different gas-liquid ...

Numerical simulation study of optimal inlet conditions of rectifier nozzle type distributor

open access: yesShipin yu jixie, 2022
Objective: In order to effectively improve or eliminate as much as possible in the refrigeration system, the uneven distribution of gas-liquid two-phase refrigerant in the evaporator leads to the performance decline of the refrigeration system.

An ultrasonic system for profiling bubblers in water [PDF]

open access: yes, 2020
Multi-phase flow occurs as two or more discrete phases flow in a closed pipe or a vessel. Examples of phases include gas, liquid or solid and also different immiscible liquids or solids[1]. Two phase flow of fluids (e.g.

Selective hydrogenation in trickle-bed reactor. Experimental and modelling including partial wetting. [PDF]

open access: yes, 2003
A steady state model of a trickle bed reactor is developed for the consecutive hydrogenation of 1,5,9-cyclododecatriene on a Pd/Al2O3 catalyst. Various experiments have shown that the selectivity of this reaction towards the product of interest is much ...

Modeling of residence time distribution : application to a three-phase inverse fluidized bed based on a Mellin transform [PDF]

open access: yes, 2009
The study is focused on modeling of gas and liquid residence time distribution in an aerated liquid system of an inverse fluidized bed bioreactor. Two opposite strategies are currently available: the use of powerful complex computational fluid dynamics ...

Mathematical model for flow regime transition conditions of gas-liquid two-phase flow in natural gas reservoir fracture

open access: yesMeitan kexue jishu
The flow of gas-liquid two-phase flow in reservoir fractures may exhibit various flow regimes, such as bubble flow, slug flow, and annular mist flow. Identifying the conditions for the transition between these flow regime is essential for understanding ...

Effect of Cluster Formation on Isospin Asymmetry in the Liquid-Gas Phase Transition Region

open access: yes, 2000
Nuclear matter within the liquid-gas phase transition region is investigated in a mean-field two-component Fermi-gas model. Following largely analytic considerations, it is shown that: (1) Due to density dependence of asymmetry energy, some of the ...
