We present an analytical model for electro-hydrodynamic flow that describes the relationship between the corona voltage, electric field, and ion charge density. The interaction between the accelerated ions and the neutral gas molecules is modeled as an external body force in the Navier-Stokes equation. The gas flow characteristics are solved from conservation principles with spectral methods. This multiphysics model is shown to match experimental data for a point-to-ring corona configuration, shedding new insights into mass, charge, and momentum transport phenomena, and can be readily implemented in any numerical simulation.
我们提出了一种用于电流体动力学流动的分析模型，该模型描述了电晕电压、电场和离子电荷密度之间的关系。加速离子与中性气体分子之间的相互作用被建模为纳维-斯托克斯方程中的外力。利用谱方法从守恒原理求解气体流动特性。结果表明，这个多物理场模型与点到环电晕配置的实验数据相匹配，为质量、电荷和动量传输现象提供了新的见解，并且可以很容易地在任何数值模拟中实现。
