WebStep 1: What in the Science Is Going On. Electrostatic wind goes by many names. Ionic wind, electric wind, or my usually favorite corona wind. The main driving force behind this concept is a high voltage source and an air gap between that source and ground. Another term for voltage is potential difference. WebF.

Ionic air propulsion is a technique for creating a flow of air through electrical energy, without any moving parts. Because of this it is sometimes described as a "solid-state" drive. It is based on the principle of electrohydrodynamics. In its basic form, it consists of two parallel conductive electrodes, a leading emitter wire and a downstream collector. When such an arrangement is powered by high voltage (in the range of kil… WebAbstract—Ionic winds are air flows that are generated when ions driven by an electric field collide with air molecules. This collision transfers momentum from the ion to the air mole-cule, thus generating a bulk flow. Typically, ionic winds are generated by gas discharges requiring large input voltages (>5 kV) applied between two electrodes. cst m2/s 変換 early help team scarborough
