Scientific paper

In this work we are going to perform a simulation of a positive corona discharge in nitrogen gas, using two different asymmetric capacitor geometries. This work represents an improvement over previous work in order to accomplish higher ion wind velocities as well as stronger electrostatic propulsion forces on all the involved electrodes. In our model, the used positive ion source is a small diameter wire, which generates a positive corona discharge in nitrogen gas directed to the ground (or negatively charged) electrodes. By applying the fluid dynamic and electrostatic theories, all hydrodynamic and electrostatic forces that act on the considered geometries will be computed in an attempt to demonstrate the greater performance of the new developed geometries.
