Drag modelling for flows through assemblies of spherical particles with machine learning: A comparison of approaches
Julia Reuter, Hani Elmestikawy, Sanaz Mostaghim +1
Drag forces on particles in random assemblies can be accurately estimated through particle-resolved direct numerical simulations (PR-DNS). Despite its limited applicability to rela…
A new paradigm for computing hydrodynamic forces on particles in Euler-Lagrange point-particle simulations
Berend van Wachem, Hani Elmestikawy, Akshay Chandran +1
Accurate prediction of the hydrodynamic forces on particles is central to the fidelity of Euler-Lagrange (EL) simulations of particle-laden flows. Traditional EL methods typically…
Self-sorting of bidisperse particles in evaporating sessile droplets
Aman Kumar Jain, Fabian Denner, Berend van Wachem
This study investigates the dispersion and self-sorting dynamics of bidisperse particles, i.e., a mixture of two distinct particle sizes, during the evaporation of ethanol droplets…
Steady undisturbed velocity correction scheme for Euler-Lagrange simulations near planar walls
Akshay Chandran, Fabien Evrard, Berend van Wachem
Euler-Lagrange (EL) point-particle simulations rely on hydrodynamic force closure models to accurately predict particle dynamics in flows. The closure models currently employed for…
Correlations for aerodynamic force coefficients of non-spherical particles in compressible flows
Christian Gorges, Victor Chéron, Anjali Chopra +2
This study presents particle-resolved direct numerical simulations using three-dimensional body-fitted hexahedral meshes to investigate the aerodynamic force and torque coefficient…
