Charge transport in flowing high resistivity liquids: periodic wire-channel configuration

摘要

The charge transport in moving weakly conducting fluids is studied numerically for a periodic structure of infinitely long cylinders between two parallel planes. An external electric field results in dissociation of impurities and generating of the electric charge. The numerical algorithm used for simulation is based on the Finite Element Method for the electric field, the Method of Characteristics for the charge transport and the Finite Volume Method for the fluid flow. The results of simulation show an effect of the fluid flow on the charge transport, and also modification of the flow characteristics caused by the electric force.
