The investigation of gas–liquid two-phase transient flow based on Steger–Warming flux vector splitting method in pipelines

Advances in Mechanical Engineering, 2016
In this article, two fluid conservation equations of gas–liquid two-phase transient flows are deduced with an improved mass transfer model between two phases and applied to liquid-column separation transients in pipelines. A new description of gas–liquid

Precise Void Fraction Measurement in Two-phase Flows Independent of the Flow Regime Using Gamma-ray Attenuation

Nuclear Engineering and Technology, 2016
Void fraction is an important parameter in the oil industry. This quantity is necessary for volume rate measurement in multiphase flows. In this study, the void fraction percentage was estimated precisely, independent of the flow regime in gas–liquid two-

Bubble flow analysis using multi-phase field method [PDF]

EPJ Web of Conferences
In simulations of gas-liquid two-phase flows using conventional interface capture methods, we observed that when bubbles come close to each other, they tend to merge numerically, despite experimental evidence indicating that they would repel each other ...

Stochastic DSMC method for dense bubbly flows: Methodology [PDF]

, 2018
A stochastic Direct Simulation Monte Carlo (DSMC) method has been extended for handling bubble-bubble and bubble-wall collisions. Bubbly flows are generally characterized by highly correlated velocities due to presence of the surrounding liquid. The DSMC

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
