CFD study of particle back-flow in pneumatic conveying systems due to triboelectrification
Otome Obukohwo, Andrew Sowinski, Poupak Mehrani +1
In industrial plants, pneumatic conveying systems are often used to convey particles from one location to another. Surprisingly, in bench-scale experiments, clusters of particles s…

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…
