Hydrodynamic Mode Coupling: Effects of density variations in nanoscale channel flows
L. Heitmeier, J. S. Hansen
We apply a modal framework for investigating the effect of density variations on gravity-type driven flows at the nanoscale. Using eigenfunction decomposition of the density and ac…
Molecular Dynamics simulations of Al-Ti metallic alloy melts using a transferable machine-learning potential
Yuna Kato, Jürgen Brillo, Dirk Holland-Moritz +4
We investigate the structural and dynamical properties of binary aluminum-titanium liquid metallic alloys, as a function of temperature and composition. We make use of MD-simulatio…
A Vibrated Compacting Granular System: A DEM Light Scattering Comparison
Linnea Heitmeier, Jan Gabriel
We perform Discrete Element Method (DEM) simulations of granular particles (polystyrene spheres) vibrated inside a cubic container. The study investigates the evolution of the pack…
Spreading droplets of yield-stress fluids with and without gravity
Linnea Heitmeier, Olfa D'Angelo, Maziyar Jalaal +1
We investigate the effect of gravity on the spreading of droplets of yield stress fluids, by performing both microgravity experiments (in a drop tower) and experiments under terres…
Shear-Rate Dependent Surface Tension of Glass-Forming Fluids
Linnea Heitmeier, Thomas Voigtmann
We investigate the interface of a glass-forming fluid showing non-Newtonian rheology. By applying shear flow in the interface, we detect that the surface tension depends on the she…
