    Development of a Supersonic Reflected Shock Tunnel
    (2017) Van Harberden, Wesley; Johansen, Craig; Ramirez-Serrano, Alex; Du, Ke; Langill, Phil
    A reflected shock tunnel capable of producing supersonic/hypersonic flows was developed. The facility as a whole is described and tested for purposes of calibration and demonstration. A method for producing diaphragms in-lab was developed, and demonstrated to produce diaphragms with good bursting characteristics. The manufacture of diaphragms was also calibrated for the purpose of aiding in future experiments using the shock tunnel. The reflected shock tube portion was tested for its ability to generate a high pressure, high temperature, reservoir gas, as required for achieving supersonic flow by means of nozzle expansion. The nozzle itself was tested by means of inserting a wedge to create an oblique shock wave, and confirmed to successfully achieve supersonic flow. Finally, the entire shock tunnel was tested and confirmed to be capable of reproducing a given set of test conditions with a high level of repeatability.
