Influence of the Reynolds number from to on size-dependent bipolar charging
Simon Jantač, Holger Grosshans
We recently found wall-bounded turbulence to suppress and control bipolar triboelectric charging of particles of identical material. This control is due to fluid modifying the moti…
Polarity switch of PMMA powder transported through a PMMA duct
Wenchao Xu, Holger Grosshans
During pneumatic conveying, powder electrifies rapidly due to the high flow velocities. In our experiments, the particles even charge if the conveying duct is made of the same mate…
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…
Simulation of the flow of an explosive atmosphere exposed to a hot surface
Subrahmanyeswara Velagala, Priyank Raval Sai Charan Singh Chowhan, Ghazaleh Esmaeelzade +2
The accidental ignition of combustible atmospheres by hot surfaces is of great concern for chemical and process plant safety. In this paper, we present our research regarding the e…
