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. WebThe neutral molecules pass through the ground electrode and generate the thrust called the ionic wind. This post summarizes work that has been done to develop ionic wind …

Webscale ionic winds can potentially enhance the bulk cooling of forced convection at the location of a hot-spot for more ef-fective and efficient cooling. Because microscale ionic wind devices i.e., “ionic wind engines” can be fabricated on an electronic chip, on a spreader, or on the skin of a notebook, Web3 apr. 2013 · When a current passes between two electrodes — one thinner than the other — it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel. This phenomenon, called electrohydrodynamic thrust — or, more colloquially, “ionic wind” — was first identified in ...
