Simulation of electron interactions with liquid water and processes related to sub-nanosecond electrical breakdown
Original language description
Sub-nanosecond electrical breakdown in dielectric liquids is of vital interest, e.g. for applicationsnin high-voltage insulation and high-current switching. Liquid dielectrics in strongnnonuniform electric fields are under influence of electrostrictive force that tends to move thenfluid into the regions with higher electric field. If the voltage rise is fast enough, the liquid doesnnot have enough time to be set into motion in order to reduce the internal stress. In this casenthe ponderomotive force induces significant stress in the bulk of the liquid which is manifestednas a negative pressure. At certain threshold, the negative pressure causes cavitation ruptures ofnthe fluid. Subsequently, free electrons can be produced by emission from the surface inside thencavity and accelerated to energies exceeding the energy for ionization of water and contributento ultrafast electrical breakdown of water.
