Two-Phase Numerical Modeling of Grade Intermixing in a Steelmaking Tundish
Metals, 2019 The sequential casting of slabs is a major trend in the steel industry where steel quality is the most important factor. The operating parameters have the most influence on mixing phenomenon apart from the design and shapes of the tundish and its ...

Modelling the effect of pipeline inclination on the multiphase flow regime
Архитектура, строительство, транспорт, 2022 The paper investigates the effect of an inclination angle of a straight pipeline on the gas-liquid two-phase flow regime at the same inlet conditions. The homogeneous Volume of Fluid (VOF) model in Ansys Fluent is used in this study for simulating the ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing
Advanced Science, EarlyView.Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Optimizing Stratification in Binary Colloidal Supraparticles
Advanced Science, EarlyView.Supraparticles from binary particle populations show stratification when dried at high Péclet numbers. In spray‐dried systems at high initial particle concentration and fast drying conditions optimal combinations of particle size ratios and volume fractions that produce maximal stratification are found both in experiment and simulation, contrasting the

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study systematically investigates the cavitation characteristics of a novel sleeve‐shaft counterrotating (SSCR) hydrodynamic cavitation reactor using computational fluid dynamics (CFD). Based on the RANS framework combined with the SST k–ω turbulence model and the Zwart–Gerber–Belamri cavitation model, the temporal–spatial evolution of ...

Volume-of-Fluid (VOF) Simulations of Marangoni Bubbles Motion in Zero Gravity
, 2012 This chapter deals with two-phase flows, i.e. systems of different fluid phases such as gas and liquid. A typical example of a two-phase flow is a motion of a particle (bubble or droplet) in a stagnant fluid (liquid or gas). In many branches of engineering it is important to be able to describe the motion of gas bubbles in a liquid (Krishna & Baten ...
