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…
Divergent Impact Charging of Polymer Particles
Simon Jantač, Holger Grosshans
When a particle contacts a surface of another material, it is commonly believed that the particle acquires an impact charge that scales inversely with its pre-impact charge and who…
The effect of discontinuous injection on particle back-flow in pneumatic conveying systems
Otome Obukohwo, Andrew Sowinski, Poupak Mehrani +1
Pneumatic conveying is used in many process industries to transport dry, granular, and powdered solids. The triboelectrification of particles during conveying causes particle agglo…
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…
