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…
