원형 실린더형 저온 플라즈마 발생관 배치에 따른 유동특성에 관한 연구

For study on the flow field of the plasma generator having a circular cylindrical shape according to the installation position in air cleaner was numerically investigated. The 2D simplified circular cylinder was analyzed in various arrangement. A pair or two pairs of plasma generator were arranged in a simulated specific area. The distance from the gap between the cylinders and case was expressed by the diameter of the cylinder as being non-dimension. The pressure drop and velocity variance caused by the cylinder was analyzed to confirm the tendency in accordance with the arrangement of the cylinders using numerical analysis. To examine the effective placement of the plasma generation quantitatively compared the total surface area of plasma generator with the surface area above a certain velocity. The analysis that the arrangement of two pairs of circular cylinders applied the appropriate arrangement of a pair of circular cylinders was carried out. The studies showed that the interaction between the plasma generators, and proposed an effective arrangement for the plasma generation.
