Spatially resolved measurement of the electrostatic charge of turbulent powder flows
Wenchao Xu, Simon Jantač, Tatsushi Matsuyama +1
This article reports on measurements of the electrostatic charge of particles in a turbulent duct flow. In contrast to previous charge measurements, which do not apply to turbulent…
Airborne Virus Transmission: Increased Spreading Due to Formation of Hollow Particles
Gizem Ozler, Holger Grosshans
The globally supported social distancing rules to prevent airborne transmission of COVID-19 assume small saliva droplets evaporate fast and large ones, which contain most viral cop…
Triboelectric Charging Model for Particles with Rough Surfaces
Simon Jantač, Jarmila Pelcová, Jana Sklenářová +3
The triboelectric charging of particles depends on the contact area of the particle and the contacting surface. Even though the surface topology determines the real contact area, p…
Suppression and Control of Bipolar Powder Charging by Turbulence
Simon Jantač, Holger Grosshans
Current models predict particles of the same material but different sizes to charge bipolar upon contacts; the resulting charge peaks endanger process safety. However, we found wal…
Effect of Drag Force Modeling on the Flow of Electrostatically Charged Particles
Gizem Ozler, Mustafa Demircioglu, Holger Grosshans
In CFD simulations of two-phase flows, accurate drag force modeling is essential for predicting particle dynamics. However, a generally valid formulation is lacking, as all availab…
