Numerical Simulation of Plasma Igniter Efflux Characteristics Based on Multi-Physical Field Coupling

Abstract To explore the chamber plasma jet ignition effect, establishment of pre-chamber based on a 3D model using method numerical simulation was carried out working process calculation. The analysis firearms in combustion characteristics provided reference for performance boost. results show that velocity at igniter outlet can reach 78 m/s and temperature 2300 K, which makes hot spread far enough reflux area ensures achieve effect heating igniting larger area. mixture air reacts with kerosene position along border, fine channel before export, speeding up export flow velocity, core region 2400 component concentration 45%, O 2 20%, H 15%, CO 7%. ratio to should be such two similar speeds mixing
