Abstract :
A numerical algorithm for simulation of the electric field, generated by charged fluid in partially filled cylindrical tanks, is presented. Originally, the fluid is uniformly charged to some level, but the charge is dissipated due to volume and surface conduction. The rate of charge dissipation is calculated by solving the current continuity equation, and the electric field distribution is also evaluated at each instant of time. Both problems are solved using the finite-element method in the time domain. The results of simulation show the effect of the surface conduction on the process dynamics.
