Microstructure-based prediction of hydrodynamic forces in stationary particle assemblies
Berend van Wachem, Hani Elmestikawy, Victor Chéron
In the work, we derive novel hydrodynamic force models to describe the interaction of a flow with particles in an assembly when only an averaged resolution of the flow is available…
Amplitude modulation of acoustic waves in accelerating flows quantified using acoustic black and white hole analogues
Sören Schenke, Fabian Sewerin, Berend van Wachem +1
We investigate the amplitude modulation of acoustic waves in accelerating flows, a problem that is still not fully understood, but essential to many technical applications, ranging…
Efficient reduction of vertex clustering using front tracking with surface normal propagation restriction
Christian Gorges, Azur Hodžić, Fabien Evrard +3
A significant computational expense and source of numerical errors in front tracking is the remeshing of the triangulated front, required due to distortion and compaction of the fr…
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…
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…
A hybrid immersed boundary method for dense particle-laden flows
Victor Chéron, Fabien Evrard, Berend van Wachem
A novel smooth immersed boundary method (IBM) based on a direct-forcing formulation is proposed to simulate incompressible dense particle-laden flows. This IBM relies on a regulari…
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…
