摘要： 在本工作中，将计算不对称电容器中产生的推进力，针对接地电极的三种不同直径进行计算。 使用的离子源是一根小直径的导线，在氮气中产生正电晕放电，导向接地电极。 通过应用流体力学和静电理论，将计算作用在所考虑几何结构上的所有流体动力学和静电力，以试图提供对作用在不对称电容器上的力机制的物理见解，并且理解如何提高推进效率。 显示英文摘要

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.
