Sharp front tracking with geometric interface reconstruction
Christian Gorges, Fabien Evrard, Robert Chiodi +2
This paper presents a novel sharp front-tracking method designed to address limitations in classical front-tracking approaches, specifically their reliance on smooth interpolation…
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…
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…
Wavelet based modeling of subgrid-scales in LES of particle-laden turbulent flows
Max Hausmann, Fabien Evrard, Berend van Wachem
We propose a novel model to obtain the subgrid-scale velocity in the context of large-eddy simulation (LES) of particle-laden turbulent flows, to recover accurate particle statisti…
Comparison of methods for curvature estimation from volume fractions
Austin Han, Fabien Evrard, Olivier Desjardins
This paper evaluates and compares the accuracy and robustness of curvature estimation methods for three-dimensional interfaces represented implicitly by discrete volume fractions o…
Drag, lift and torque correlations for axi-symmetric non-spherical particles in locally non-uniform flows
Victor Chéron, Fabien Evrard, Berend van Wachem
This paper derives new correlations to predict the drag, lift and torque coefficients of axi-symmetric non-spherical rod-like particles for several fluid flow regimes and velocity…
A large eddy simulation model for two-way coupled particle-laden turbulent flows
Max Hausmann, Fabien Evrard, Berend van Wachem
In this paper we propose a new modeling framework for large eddy simulations (LES) of particle-laden turbulent flows that captures the interaction between the particle and fluid ph…
Spectral response between particle and fluid kinetic energy in decaying homogeneous isotropic turbulence
Martin Schiødt, Azur Hodzic, Fabien Evrard +3
In particle-laden turbulence, the Fourier Lagrangian spectrum of each phase is regularly computed, and analytically derived response functions relate the Lagrangian spectrum of the…
Phase proper orthogonal decomposition of non-stationary turbulent flow
Yisheng Zhang, Azur Hodzic, Fabien Evrard +2
A phase proper orthogonal decomposition (Phase POD) method is demonstrated, utilizing phase averaging for the decomposition of spatio-temporal behaviour of statistically non-statio…
Reducing volume and shape errors in front tracking by divergence-preserving velocity interpolation and parabolic fit vertex positioning
Christian Gorges, Fabien Evrard, Berend van Wachem +1
Volume conservation and shape preservation are two well-known issues related to the advection and remeshing in front tracking. To address these issues, this paper proposes a diverg…
Characterizing Lagrangian particle dynamics in decaying HIT using proper orthogonal decomposition
Martin Schiødt, Azur Hodzic, Fabien Evrard +2
The particle proper orthogonal decomposition (PPOD) is demonstrated on cases of particle flows in decaying homogeneous isotropic turbulence. Data is generated through one-way coupl…
