This is the second part of a two-part paper describing the operating characteristics of the electric arc-driven shock-tube facilities at NASA Ames Research Center. This part discusses the performance of the driven sections when the facility is used as a tool to produce a low-density nonequilibrium flow and when used as a shock tunnel. Specifically, the paper discusses the cleanliness of the driven flow at low densities, and the deviation from the equilibrium conditions at the test section of the shock-tunnel flow.
