Numerical calculation of current distribution due to spark discharge on water surface with surface potential as boundary condition

Numerical calculations of current distribution due to spark discharge on water surface of 0.07 S/m and 5 S/m conductivity were done using two-dimensional axial-symmetry model. In this work, only the water phase is taken into account as the first step to a complete two-phase gas-liquid model. Electri...
