Gas-liquid plug flow liquid holdup measurement using semantic segmentation
Liquid holdup is one of the most important parameters of gas-liquid two-phase flow. Affected by the image noise, the traditional liquid holdup measurement method based on image processing is difficult to accurately extract the gas-liquid interface ...

Detection of the gas–liquid two-phase flow regimes using non-intrusive microwave cylindrical cavity sensor [PDF]
Gas–liquid two-phase flow phenomenon occurs in various engineering applications and the measurement of it is important. A microwave sensor in the form of a cylindrical cavity has been designed to operate between 5 and 5.7 GHz. The aim is to analyse a two

An ultrasonic system for profiling bubblers in water [PDF]
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.

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

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

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