Unsteady Numerical Simulation of the 1 MW Radiatively-Driven Hypersonic Wind Tunnel Experiment Conference Paper uri icon


  • In this paper, results are discussed of time accurate predictions for an experiment in which a 1MW electron beam deposits its energy in a supersonic flow. Studies and predictions for different cases to compare wall pressure distribution, exit velocity and density are presented. The Radiatively-Driven Hypersonic Wind Tunnel (RDHWT) experiments are being carried out collaboratively by Princeton University and the Sandia National Laboratory. The purpose of the experiments is to demonstrate the viability of the energy addition concept at approximately a ten times higher level of electron beam power (1MW) than was attempted previously (15). The experiments have been conducted to validate existing energy-addition models and to develop further an understanding of the physics involved in the addition of electron beam energy to supersonic flows. In a companion paper (AIAA 2004-1134) we discuss the extensive experimental work that has been done.
