A collision model for DNS with ellipsoidal particles in viscous fluid
Ramandeep Jain, Silvio Tschisgale, Jochen Fröhlich
The article proposes an algorithm to model the collision between arbitrary ellipsoids in viscous fluid. It is composed of several steps, each improving upon the standard procedure…
Scale-dependent anisotropy, energy transfer and intermittency in bubble-laden turbulent flows
Tian Ma, Bernhard Ott, Jochen Frohlich +1
Data from Direct Numerical Simulations of disperse bubbly flows in a vertical channel are used to study the effect of the bubbles on the carrier-phase turbulence. A new method is d…
Analysis of the Near-Wall Flow in a Turbine Cascade by Splat Visualization
Baldwin Nsonga, Gerik Scheuermann, Stefan Gumhold +3
Turbines are essential components of jet planes and power plants. Therefore, their efficiency and service life are of central engineering interest. In the case of jet planes or the…
Efficient modelling of particle collisions using a non-linear viscoelastic contact force
Shouryya Ray, Tobias Kempe, Jochen Fröhlich
In this paper the normal collision of spherical particles is investigated. The particle interaction is modelled in a macroscopic way using the Hertzian contact force with additiona…
