Modeling of granular media with electrostatic interactions
In granular materials composed of sub-millimeter particles, electrostatic charges can arise due to multiple contacts and friction. These charges result in attractive or repulsive interactions, playing a significant role in flow behavior and agglomeration phenomena [1]. Electrostatic interactions often have a negative impact on powder processing operations, due to issues such as particle agglomeration, dust accumulation on surfaces, or equipment clogging. These effects are also critical in space exploration, where in the absence of water, fine particles easily adhere to measuring instruments, impairing their functionality.
