Characterization of a Glow Discharge in a Tripped Hypersonic Boundary Layer

What is it about?

A DC glow discharge plasma was generated in a hypersonic boundary layer. The effect of the flow conditions, order of the electrodes, and the inclusion of trips were all independently studied. The main diagnostics were power measurement, visual observation, and optical emission spectroscopy. These data, the first known to the authors to be available for a tripped hypersonic boundary layer, are intended to aid in the design of analogous plasma applications.
