Description

  • Content Description: The purpose of this feasibility study was to conduct preliminary modeling to elucidate the mechanisms responsible for the effects observed in the Air Force Research Laboratory (AFRL) shock tube experiment. It was assumed that the plasma is simply a region of gas in the shock tube that has a higher gas temperature. Computational fluid dynamics (CFD) calculations were performed to simulate the propagation of a shock wave through the tube, using the same parameters in the experiment. Both 1- D and 3-D CFD calculations were performed to determine which effects can be explained simply by axial temperature gradients and which effects require the presence of radial temperature gradients. Discharge plasma physics calculations of a longitudinal glow discharge were then used to establish if the electrical currents used in the experiment are consistent with the gas temperature distributions that are necessary to explain the observed effects.
