サーモグラフィを用いた静電冷却場の可視化 Visualization of Electrostatic Cooling Field by Thermography 坂口, 勝次 43076 石岡, 泰和 43077 井戸, 優 43078 南山, 龍緒 43079 サーモグラフィ 静電冷却 可視化 熱伝達 Thermography Electrostatic Cooling Visualization Heat Transfer P(論文) The experimental study on the electrostatic cooling was carried out by using a thermography. The DC corona discharge was occurred between a needle and a flat plate electrode under the applied negative high voltage ranged from -7 to -50 kV and the needle-plate gap varied from 15 to 50 mm. The temperature field of the plate electrode was measured by a infrared scanner and the surface temperature distributions of the plate electrode were evaluated and visualized by a thermography system. The local heat transfer coefficients near the stagnation point were enhanced with increasing the applied voltage against the natural convective heat transfer field, while were decreased under the considerably higher voltage. departmental bulletin paper 1998-09 application/pdf 福山大学工学部紀要 1 22 61 66 AN00217655 https://fukuyama-u.repo.nii.ac.jp/record/8034/files/KJ00005781404.pdf https://fukuyama-u.repo.nii.ac.jp/records/8034 jpn
