Secondary flows drive triboelectric powder charging in pneumatic conveying

Gizem Ozler, Holger Grosshans

Highly resolved simulations reveal the fundamental influence of a carrier fluid's flow dynamics on triboelectric powder charging. We found that particles transported through a squa…

Unmasking hidden ignition sources: A new approach to finding extreme charge peaks in powder processing

Holger Grosshans, Wenchao Xu, Simon Jantač +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…
