Numerical Simulation of Positive Streamer in Non-uniform Electric Field of Centimeters Gap
A quas-one-dimensional equivalent numerical model is established to simulate the progression of streamer in non-uniform field
and to overcoming the shortage of non-uniform field of two-dimensional streamer simulation
in which the numerical solution is complex and hard to converge. Based on the equivalent model of the streamer development
the process of positive development streamer of typical rod-plane gap with clearance of order of centimeter is studied. The variation characteristics of micro-physical parameters of spatial electric field
electric potential
charge density distribution and streamer speed are obtained. The effect of streamer channel shape on the physical characteristics of streamer discharge is also discussed and the reasonable principles on the choice of streamer channel shape are determined.
