  In this work we are going to perform a simulation of a wire-cylinder-plate
positive corona discharge in nitrogen gas, and compare our results with already
published experimental results in air for the same structure. We have chosen to
simulate this innovative geometry because it has been established
experimentally that it can generate a thrust per unit electrode length
transmitted to the gas of up to 0.35 N/m and is also able to induce an ion wind
top velocity in the range of 8-9 m/s in air. In our model, the used ion source
is a small diameter wire, which generates a positive corona discharge in
nitrogen gas directed to the ground electrode, after which the generated
positive ions are further accelerated in the acceleration channel between the
ground and cathode. 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 theoretically confirm the generated ion wind
profile and also the thrust per unit electrode length. These results are
important to establish the validity of this simulation tool for the future
study and development of this effect for practical purposes.
