Effect of Reynolds number on triboelectric particle charging in turbulent channel flow
Christoph Wilms, Holger Grosshans
Triboelectric charging in particle-laden flows is a complex interplay of fluid and particle dynamics, collision mechanics, and electrostatics. In this study, we introduce triboFoam…

ML enhanced measurement of the electrostatic charge distribution of powder conveyed through a duct
Christoph Wilms, Wenchao Xu, Gizem Ozler +3
The electrostatic charge acquired by powders during transport through ducts can cause devastating dust explosions. Our recently developed laser-optical measurement technique can re…

Unmasking hidden ignition sources: A new approach to finding extreme charge peaks in powder processing
Holger Grosshans, Wenchao Xu, Simon JantaÄ +1
Powders acquire a high electrostatic charge during transport and processing. Consequently, in the aftermath of dust explosions, electrostatic discharge is often suspected to be the…
