Abstract

Ionic wind is produced by a corona discharge when a DC high voltage is applied across the point-to-plane gap geometry. The corona discharge phenomena have been investigated in several beneficial application fields such as electrostatic cooling, ozone generation, electrostatic precipitation and electrostatic spraying. Recently ionic wind might be used in aerodynamic, for example, heat transfer, airflow modification, and etc. In this work, in order to analyze the control behavior of the velocity and amount of ionic wind produced by the positive DC corona discharges. The ionic wind velocity was measured as a function of the applied voltage, diameter of the punched hole on plate electrode and separation between the point-to-plate electrodes. As a results, the airflow is generated from the tip of needle to the plate electrode in the needle-to-punched-plate electrode systems. The ionic wind velocity is linearly increased with an increase in applied voltage and ranges from 1 to 3 m/sec at the locations of 100-200 mm from the punched-plate.

직류 고전압이 침 대 평판전극에 인가된 불평등전장에서 코로나방전이 발생하게 되면 하전입자들의 이동에 의한 이온풍이 발생한다. 코로나 방전현상은 오존발생장치, 전기집진장치, 정전 냉각과 도색 등의 응용분야에서 다각도로 연구되어 왔으며, 최근 이온풍은 열전달장치, 공기순환장치 등에 이용되기도 한다. 본 연구에서는 침 대 중공평판전극에 직류 고전압을 인가하였을 때 발생하는 이온풍의 속도와 풍량의 제어 특성을 분석할 목적으로 인가전압, 중공의 크기, 전극간 거리의 변동에 따른 풍속의 변화를 측정하였다. 결과로서 이온풍에 의한 기류가 침전극으로부터 평판전극을 향하는 방향으로 발생하였으며, 중공평판전극의 후면의 100~200 [mm]지점에서 측정한 이온풍의 풍속은 인가전압에 따라 1~3[㎧]의 범위에서 증가하였다.
