Fluid mechanics of a Mach 7-12, electron-beam driven, missile-scale hypersonic wind tunnel: Modeling and predictions Conference Paper uri icon

abstract

  • Models of increasing complexity have been developed for the design and simulation of the axisymmetric inviscid fluid mechanics and energy addition of an Electron Beam Driven Hypersonic wind-tunnel for missile scale testing and development. The principal target has been a Mach 12 capability at altitudes above 25 km with a test-section of 1.3m. Also, results for lower Mach numbers at lower altitudes down to Mach 7 at 2 km have been obtained. The final fully coupled e-beam and Euler flow simulation shows that with the calculated magnetic fields, a 3 MeV e-beam source and a nozzle geometry determined from the solution to an optimization problem, shock waves can be eliminated notwithstanding the very high radiative power (200 MW) that is deposited into the core flow (away from the boundary layer). While there remain many issues to be resolved we have not yet found an intrinsic problem with the concept and its application to such long run time, missile scale, facilities. 2001 by Princeton University.
