The 2024 Annual Meeting of the Electrostatics Society of America  - June 9 - 13, 2024

About the 2024 Annual Meeting of the Electrostatics Society of America (ESA)

The 2024 Annual Meeting of the Electrostatics Society of America (ESA) is scheduled for June 9-13, 2024, at the University of Ottawa in Canada.

The Electrostatics Society of America (ESA) is hosting its 2024 Annual Meeting, where presentations and paper contributions are invited in all scientific and technical areas related to electrostatics. These areas include fundamental physics, new developments, and applications in various fields such as industry, atmospheric and space sciences, biology, medicine, energy, and other sectors that utilize electrostatic phenomena.

Presentation - Powder Tribocharging: Measurement, DEM Simulation with Patchy Particles, and Process Optimization

When two objects are rubbed against each other, they charge because of the triboelectric effect. This effect is significant in powders due to the large rate of collisions between particles during a flow. Measuring and understanding this phenomenon, and its consequences, remains a challenge. In this presentation, Geoffroy Lumay, co-founder of Granutools and Professor at the University of Liège, propose a method based on a combination of measurements with GranuCharge and numerical simulations. The GranuCharge is an original laboratory instrument measuring the ability of a powder to charge electrostatically during a flow. The numerical simulations are performed with a customised DEM code that includes the latest theoretical models describing tribocharging. This method provides a better understanding of charge buildup during continuous manufacturing processes in pharmaceutical industries, dust adhesion on solar panels, and more dramatically, dust explosions in industries.
