Analysis of Temperature Sensitivity Parameters in Hydrodynamic Model of Streamer

Temperature is an important environmental factor affecting streamer discharge. However, the mechanism and regularity of influence are still unclear. This paper analyzes how parameters in hydrodynamic model affected by temperature finite element method used to solve three particle continuity equations along with Poisson’s equation simultaneously. The results show that increase inhibits ionization attachment process, reduction rate coefficient 40 times numerically, which means easier initiate at low temperatures. accelerates diffusion drift electrons. effect increases average velocity streamer, about 4.89m/( $\text{s}\cdot \text{K}$ ) temperature, fast-moving charged particles high may affect discharge signals. essence on physical quntities its ionization, attachment, diffusion, effects. this can comprehensively consider effects obtain micro-process contributing research insulation design power equipment
