Shadow Graph Movie 1
Shadowgraph movie of e-beam heated flow made from 32 images taken 50 miocroseconds apart with an exposure of 5 microseconds. The electron beam irradiates flow for 750 microseconds and measurements of change in total enthalpy show that approximately 10 KW of e-beam power is deposited into the flow. Approximately 50 KW enters the nozzle and most of the power is lost on the nozzle walls. Flow is from the bottom to top of page and the Mach angle of the shock wave created by a small cone is observed to increase with the increase in Mach number. The Mach number decreases from 3.9 to 3.2.
