Characteristics of Sparkover Discharge In Flowing Gas with Variation of Temperature

This paper reports the characteristics of sparkover discharge in flowing air with variation of Temperature(T). Also, We studied changes of discharge pattern for constant input power by adjustment of the Reynolds number(Re) and T. The essentiales of this paper are as followers. The invaluable equation obtained from this experiment is [%]$\frac{Vs}{Re}$=A+B${\varepsilon}^{c{\cdot}Re}$ where A=10.5 B=120 $C=-3.00{\times}10^{-5}$ Breakdown Voltage for Variation of temperature in static air is given by expression Vs = K (23.98 ${\rho}$d+6.8 ${\sqrt}{{\rho}d}$)[kV] The discharge pattern can be controlled by adjustment of the Reynolds number.
