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…
