Divergent Impact Charging of Polymer Particles
Simon JantaÄ, 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…
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…
Spatially resolved measurement of the electrostatic charge of turbulent powder flows
Wenchao Xu, Simon JantaÄ, 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…
Suppression and Control of Bipolar Powder Charging by Turbulence
Simon JantaÄ, 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…
