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…
Physically consistent immersed boundary method: a framework for predicting hydrodynamic forces on particles with coarse meshes
Max Hausmann, Hani Elmestikawy, Berend van Wachem
In the present paper, a fluid-particle coupling method is directly derived from the Navier-Stokes equations (NSE) by applying the concept of volume-filtering, yielding a physically…
Drag, lift, and torque correlations for axi-symmetric rod-like non-spherical particles in linear wall-bounded shear flow
Victor Chéron, Berend van Wachem
This paper presents novel correlations to predict the drag, lift, and torque coefficients of axi-symmetric non-spherical rod-like particles in a wall-bounded linear shear flow. The…
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…
Study and derivation of closures in the volume-filtered framework for particle-laden flows
Max Hausmann, Victor Chéron, Fabien Evrard +1
The volume-filtering of the Navier-Stokes equations allows to consider the effect that particles have on the fluid without further assumptions, but closures arise of which the impl…
Simulating interfacial flows: a farewell to planes
Fabien Evrard, Robert Chiodi, Berend van Wachem +1
Over the past decades, the volume-of-fluid (VOF) method has been the method of choice for simulating atomization processes, owing to its unique ability to discretely conserve mass.…
