We designed and evaluated two cylindrical corona chargers, each of which had a central corona needle electrode. For the performance evaluation of each corona charger the polydisperse dioctyl sebacate(DOS) particles, with diameters of 0.1～0.8 mm, and NaCl particles, smaller than 0.1 mm, were used. The particles were then led through an electrostatic classifier (TSI model 3081) to classify monodisperse aerosol with minimal size deviation. After evaluating the wall loss of the particles in the corona charger, we measured the product of penetration and number of charges, , to evaluate the corona charger efficiency at high positive voltages of 4, 5, 6 kV. 대한기계학회 실시간 미세입자 측정을 위한 다이오드형 코로나 하전기의 설계 및 성능평가 Design and Performance Evaluation of a Diode Type Corona Charger for Real-Time Measurement of the Submicron Aerosol Article 2 대한기계학회논문집 B, v.28, no.9, pp.1066 - 1074 대한기계학회논문집 B 28 9 1066 1074 kci ART000937158 Electrical Low Pressure Impactor(전기적 저압 임팩터) Real-Time(실시간) Corona Charger(코로나 하전기) Monodisperse Aerosol(단분산 입자) Electrical Low Pressure Impactor(전기적 저압 임팩터) Real-Time(실시간) Corona Charger(코로나 하전기) Monodisperse Aerosol(단분산 입자)
