Results from Particle-Resolved Simulations
Agathe Chouippe, Aman G. Kidanemariam, Jos Derksen +2
We review some of the results obtained to date with the aid of the PR-DNS approach to turbulent particulate flows. It is shown that the method has matured to a point which allows t…
Heat and water vapor transfer in the wake of a falling ice sphere and its implication for secondary ice formation in clouds
Agathe Chouippe, Michael Krayer, Markus Uhlmann +3
We perform direct numerical simulations of the settling of an ice sphere in an ambient fluid accounting for heat and mass transfer with the aim of studying in a meteorological cont…
On the influence of forced homogeneous-isotropic turbulence on the settling and clustering of finite-size particles
Agathe Chouippe, Markus Uhlmann
We investigate the motion of heavy particles with a diameter of several multiples of the Kolmogorov length scale in the presence of forced turbulence and gravity, resorting to inte…
Clustering and preferential concentration of finite-size particles in forced homogeneous-isotropic turbulence
Markus Uhlmann, Agathe Chouippe
We have performed interface-resolved direct numerical simulations of forced homogeneous-isotropic turbulence in a dilute suspension of spherical particles in the Reynolds number ra…
Columnar structure formation of a dilute suspension of settling spherical particles in a quiescent fluid
Sander G. Huisman, Thomas Barois, Mickaël Bourgoin +6
The settling of heavy spherical particles in a column of quiescent fluid is investigated. The performed experiments cover a range of Galileo numbers ()…
Forcing homogeneous turbulence in DNS of particulate flow with interface resolution and gravity
Agathe Chouippe, Markus Uhlmann
We consider the case of finite-size spherical particles which are settling under gravity in a homogeneous turbulent background flow. Turbulence is forced with the aid of the random…
