Two-phase flow meter for determining water and solids volumetric flow rate in vertical and inclined solids-in-water flows

Multiphase flow can be defined as the simultaneous flow of a stream of two or more phases. Solids-in-water flow is a multiphase flows where solids and liquid are both present. Due to the density differences of the two phases, the results for such flow is

Slug Velocity Measurement and Flow Regime Recognition Using Acoustic Emission Technology [PDF]

, 2013
Slug velocity measurement and flow regime recognition using acoustic emission technology are presented. Two non-intrusive and three intrusive methods were employed to detect the slug regime and measure its velocity using AE sensors. For the non-intrusive

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

A new inversion method for water holdup of gas-water two-phase slug flow in inclined shale gas wells

Youqicang pingjia yu kaifa
Slug flow is a common flow pattern of the distribution of gas-water two-phase media in inclined shale gas wells. Monitoring the dynamics of gas-water two-phase flow under slug flow conditions, accurately inverting the distribution of gas-water media in ...

Simulating Two-Phase Seepage in Undisturbed Soil Based on Lattice Boltzmann Method and X-ray Computed Tomography Images

Sensors
The two-phase seepage fluid (i.e., air and water) behaviors in undisturbed granite residual soil (U-GRS) have not been comprehensively studied due to a lack of accurate and representative models of its internal pore structure.

Experimental and Numerical Investigation of Two-Phase Flow through Enlarging Singularity

, 2012
Gas-liquid flow is extensively used in industrial systems such as power generation units, cooling and heating systems (i.e. condensers, evaporators and manifolds), safety valves, etc.

Active control of hydrodynamic slug flow [PDF]

, 2013
Multiphase flow is associated with concurrent flow of more than one phase (gas-liquid, liquid-solid, or gas-liquid-solid) in a conduit. The simultaneous flow of these phases in a flow line, may initiate a slug flow in the pipeline. Hydrodynamic slug flow

Oil-gas-water three-phase upward flow through a vertical pipe: Influence of gas injection on the pressure gradient

, 2012
LtdAn experimental study of three-phase flow in a vertical pipe with 50 mm diameter has been carried out. The experiments were conducted under the input superficial phase velocity: water from 0 to 0.885 m/s, oil from 0 to 0.90 m/s and gas from 0 to 0.85 ...
