Radiatively driven wind tunnel experiment with a 30 kW electron beam Conference Paper uri icon


  • 1999 by Princeton University. Controlled energy addition to a supersonic flow has been demonstrated using a 1 MeV electron beam (e-beam). Within, the duration of the e-beam pulse (500-750 s) the increase in total enthalpy, absorbed power, and change in Mach number with time were measured during the heating process. Time resolved shadowgraph images show a steady transition from the unheated flow to the e-beam heated flow, demonstrating that on the time scale of these experiments a stable flow, with a higher total enthalpy, was achieved with heat addition from an electron beam.
