“…[5,6]. Among them, a regime of electrothermal acceleration, in which a flow is electrically heated, usually by arc discharge, and then aerodynamically accelerated through a nozzle, is primarily used in material processing (as plasmajets) [7,8], space propulsion systems (as arcjet thrusters) [6,9], and arc-heated wind tunnel facilities [10]. With the electrothermal acceleration, since input powers into the flow can be electrically controlled with the control of discharge currents, total temperatures, or namely velocities, can be actively controlled.…”

In this study, numerical simulation on acceleration characteristics of a supersonic free jet through utilization of a plasmajet was conducted, where the supersonic free jet was accelerated through an interaction in a shear layer between the free jet and plasmajet. In this analysis, the governing equations including two-dimensional compressible Reynolds-averaged Navier-Stokes equations (RANS) were calculated with a commercial code, ANSYS Fluent v. 14.5. As for the turbulence model, a k-ε realizable turbulence model was employed. In this paper, when a plasma flow is used for the center nozzle, the velocity is higher especially in potential core part than in the case of unheated flow because of a hot core flow of the plasmajet.
