Consistent closure modeling in large eddy simulations by direct approximation of the filtered advection term
Max Hausmann, Berend van Wachem
This article addresses the widely overlooked conceptual inconsistency of the large eddy simulation (LES) framework, namely that the commonly used advection term introduces higher w…
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…
A new paradigm for wall-modeled large eddy simulations using the volume-filtering framework
Max Hausmann, Berend van Wachem
In the present paper, we apply the framework of volume-filtering for particle-laden flows, to large eddy simulations (LES) of wall-bounded flows leading to a new perspective on wal…
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…
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…
