Spiral motion enables simultaneous homogenization and enhanced transport in granular pipe flow
Wing To Ku, Patric Mueller, Thorsten Poeschel
Density waves in gravity-driven granular pipe flow reduce transport efficiency and produce large fluctuations in the local solid fraction. Helical wall textures suppress these inst…
Helical pipes homogenize particle transport in pneumatic conveying
Wing To Ku, Patric Mueller, Thorsten Poeschel
Pneumatic conveying at moderate gas velocities can result in strongly heterogeneous particle transport, with slow particles accumulating near the bottom of the pipe while faster pa…
Rapid generation of relaxed centimeter-sized drops by capillary auto-ejection
Patric Mueller, Kai Ihrig, Achim Sack +2
Many microgravity experiments require centimeter-sized spherical liquid drops. In drop-tower experiments, only a few seconds of microgravity are available, so the drops must be gen…
Why the Multi-Sphere Shape Generator Works: Medial-Axis Placement of Spheres
Arash Moradian, Felix Buchele, Thorsten Poeschel
The Multi-Sphere Shape Generator (MSS) [1] places spheres according to a feature-enhanced residual field, but the geometric basis of this strategy has remained unknown. We prove th…
DEM simulation of the powder application in powder bed fusion
Vasileios Angelidakis, Michael Blank, Eric J. R. Parteli +4
The packing behavior of powders is significantly influenced by various types of inter-particle attractive forces, including adhesion and non-bonded van der Waals forces [1, 2, 3, 4…
Can Minkowski tensors of a porous microstructure characterize its permeability?
Prapanch Nair, Sebastian Mühlbauer, Shantanu Roy +1
We show that the permeability of porous media can be reliably predicted from the Minkowski tensors (MTs) describing the pore microstructure geometry. To this end, we consider a lar…
