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…
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…
A Novel Apparatus For Particle-Particle Single Contact Electrification Experiments
Otome Obukohwo, Simon Jantač, Andrew Sowinski +2
The experiment of a single contact between two sub-centimeter high-speed particles is often difficult to execute, especially if the collision must be physically and electrically is…
Unifying same- and different-material particle charging through stochastic scaling
Holger Grosshans, Gizem Ozler, Simon Jantač
Triboelectric charging of insulating particles through contact is critical in diverse physical and engineering processes, from dust storms and volcanic eruptions to industrial powd…
Influence of the particle distribution on dust explosions in the 20 L sphere
Kasun Weerasekara, Stefan H. Spitzer, Sabine Zakel +1
It is essential to standardize the safety characteristics of dust explosions to mitigate their impact on the process industries. The 20 L sphere primarily investigates the safety c…
