摘要:
在这项工作中,在一个不对称的电容器中开发的推进力将计算为三个不同直径的接地电极。所使用的离子源是小直径导线,其在导向接地电极的氮气中产生正电晕放电。通过应用流体动力学和静电理论,所有的流体动力学和静电力的考虑的几何形状上的作用将被计算,试图提供一个物理洞察力的机制,作用在不对称的电容器,并了解如何提高推进的效率。
英文摘要:
In this work the propulsion force developed in an asymmetric capacitor will be calculated for three different diameters of the ground electrode. The used ion source is a small diameter wire, which generates a positive corona discharge in nitrogen gas directed to the ground electrode. 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 provide a physical insight on the force mechanism that acts on the asymmetrical capacitors, and also to understand how to increase the efficiency of propulsion.
