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…
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…
A semi-analytical transient undisturbed velocity correction scheme for wall-bounded two-way coupled Euler-Lagrange simulations
Akshay Chandran, Fabien Evrard, Berend van Wachem
In the present paper, we model the velocity disturbance generated by a regularized forcing near a planar wall, which, along with the temporal nature of the forcing, provides an est…
Undisturbed velocity recovery with transient and weak inertia effects in volume-filtered simulations of particle-laden flows
Fabien Evrard, Akshay Chandran, Ricardo Cortez +1
In volume-filtered Euler-Lagrange simulations of particle-laden flows, the fluid forces acting on a particle are estimated using reduced models, which rely on the knowledge of the…
