A Study on Sparkover Discharge Characteristics of Flowing Gas

Flowing Gas의 방전특성에 관한 연구

This paper reports the characteristics of sparkover discharge in flowing gas ranging from 0[m/s] to 30[m/s] under the needle-rod gap. The important results obtained from this paper are as followers. 1. The maximum sparkover voltage of flowing gas are about 3.1[kv](d=1[cm], 5.4[kv](d=2[cm]), 8.1[kv](d=3[cm]) higher than those of static gas 2. The empirical equation obtained from this experiment is [%]$\frac{Vs}{Re}=A\;log_{10}\;Re+B$ where A=$-7.79{\times}10$ B=$5.60{\times}10^2$ 3. The duration time of sparkover decreases with increasing the Reynolds number. 4. The discharge pattern can be controlled by adjustment of the Reynolds number
