Numerical Analysis of Interaction Between Plasma Jet and Flame in Supersonic Flow

The ability of a plasma torch as an igniter in a supersonic flow for new engines was analyzed in various ways such as zero-dimensional analysis of ignition delay, one-dimensional analysis of burning velocity, and two-dimensional analysis of ignition phenomena with full chemistry, and so on. Problems in those analyses for accurate prediction of the performance of the plasma torch were herein discussed. The two-dimensional analysis was sufficient only for the ignition phenomena of the plasma torch. However, three-dimensional analysis is needed for simulations of flame spreading and flame-holding around the plasma jet after ignition.
