Description
technical field [0001] The invention relates to the field of gas discharge, in particular to a device and method for researching the characteristics of ion wind flow. Background technique [0002] A high voltage is applied between the corona electrode and the collector electrode with greatly different curvature radii to induce air ionization near the electrode with a small curvature radius, which is the so-called corona discharge phenomenon. The ion air flow acceleration device is to use the ion movement during air discharge to generate air flow and drive the movement of surrounding neutral gas molecules to achieve air flow acceleration. The essence of the mechanism of the ion wind air accelerator is the process of corona discharge of air molecules, inducing ionization of neutral particles in the air and producing airflow movement. [0003] Since the British Hauksbee discovered the ion wind phenomenon in 1709, many scholars have studied the phenomenon, and it was not until ...
