Optimization of gas–liquid two-phase flow law and structural parameters of Laval supersonic atomizing nozzle

The Physics of Fluids
In order to get rid of the dilemma of gas well fluid accumulation in the gas field, we propose an innovative scheme of using Laval nozzle as a downhole atomizing nozzle for atomized drainage gas extraction.

Distribution of gas-liquid two-phase flow in parallel microchannels with the splitting of the liquid feed

, 2020
The instability of gas-liquid two-phase flow caused by bubble collision downstream in parallel microbranching T-junctions is discovered, and a strategy of splitting liquid feed stream in two for the prevention of bubble collision is proposed.

An Interdigital Conductance Sensor for Measuring Liquid Film Thickness in Inclined Gas–Liquid Two-Phase Flow

IEEE Transactions on Instrumentation and Measurement
This study proposes an interdigital conductance sensor (ICS) for measuring the thickness of a liquid film with a nonuniform distribution of inclined gas–liquid two-phase flow.

Two-phase gas–liquid flow in horizontal corrugated channels

International Journal of Multiphase Flow, 2000
Abstract Experiments have been carried out for adiabatic concurrent gas–liquid flow of nitrogen and water through two corrugated test sections. This study examines flow patterns as the gas fluxes are increased. At low gas fluxes two main patterns have been observed: stratified flow for low liquid fluxes and bubble flow for greater ones. The mean wall

Measurement of vertical gas-liquid two-phase flow by electromagnetic flowmeter and image processing based on the phase-isolation

Experimental Thermal and Fluid Science, 2019
In this paper, the electromagnetic flowmeter and the image processing are used to measure vertical gas-liquid two-phase flow. In order to reduce the effect of randomly distributed bubbles on the weight function of the electromagnetic flowmeter and the ...

Gas-liquid two-phase flow in a square microchannel with chemical mass transfer: Flow pattern, void fraction and frictional pressure drop

International Journal of Heat and Mass Transfer, 2018
The dynamics of the gas-liquid two-phase flow are of great significance for the heat and mass transfer performance in a microreactor. In this paper, the flow pattern, void fraction and frictional pressure drop of gas-liquid two-phase flow of CO2 and MEA/[

The effect of flow distribution on mass transfer of gas-liquid two-phase flow in two parallelized microchannels in a microfluidic loop

International Journal of Heat and Mass Transfer, 2019
The gas-liquid two-phase flow distribution and mass transfer performance of CO2 absorption into 2-amino-2-methyl-1-propanol (AMP) with ethylene glycol (EG) in two parallelized microchannels in a microfluidic loop were investigated.

Gas-liquid contacting in vertical two-phase flow

Industrial & Engineering Chemistry Process Design and Development, 1985
Deep shaft reactors (DSR's) employ vertical two-phase bubbleflow to effect mass transfer between gases and liquids. Mass transfer coefficients in these devices are high, and the large pressures at the base of the reactor serve to promote gas dissolution.
