Summary:

Electrohydrodynamic (EHD) technology, noted for its absence of moving mechanical parts and silent operation, has attracted significant interest in plane propulsion. However, its low thrust and efficiency remain key challenges hindering broader adoption. This study investigates methods to enhance the propulsion and efficiency of EHD systems, by examining the electrohydrodynamic flow within a wire-cylinder corona structure through both experimental and numerical approaches. A multi-wire-cylinder positive corona discharge experimental platform was established using 3D printing technology, and measurements of flow velocity, voltage, and current at the cathode outlet were conducted. A two-dimensional simulation model for multi-wire-cylinder positive corona discharge was developed using Navier-Stokes equations and FLUENT user-defined functions (UDF), with the simulation results validated against experimental data. The analysis focused on the effects of varying anode diameters and the distances between the anode and cathode on flow velocity, voltage, and current, as well as the influence of charge density intensity and distribution of ionic wind and flow velocity. The experimental results demonstrated that an anode diameter of 0.3 mm yielded the highest flow velocity, reaching 0.94 m/s. Additionally, the study highlighted the critical role of charge density in enhancing flow velocity, showing that increased charge density could improve propulsion and efficiency. These findings suggest that optimizing charge density and electrode parameters can potentially overcome the current efficiency limitations of EHD engines, paving the way for their broader application in propulsion systems
