INVESTIGATION OF SPHERICAL SHOCK WAVES IN A SHOCK TUBE
Abstract
A shock tube was constructed for investigating spherical shock waves in various atmospheres. The shock tube was carefully calibrated for its performance throughout the designed operating range. Thin-film heat transfer gauges were employed to measure the speed of the incident shock wave. Shadowgraph technique was used to establish the geometry of the spherical shock waves which were produced by either allowing the center portion of the incident shock to enter an orifice and then allowing it to expand into a spherical shock wave at the entrance of the orifice upon reflection from the end or utilizing the high temperature, high enthalpy gas behind the reflected shock wave to expand through a conical nozzle. Attempts were made to measure the speed of the spherical shock waves. (Author)
