Physics Guided Simulation of Electrostatic Discharge: Technical Report Open
Triboelectrically-charged objects may create threshold sparks, electrostatic discharge (ESD) events, to equilibrate charge between themselves and other relatively charged objects. ESD events exhibit many complex physical phenomena. They ar…
