Analytical, Numerical, and Experimental Investigations of Oblique-Shock-Wave Reflections in Pure and Dusty Gases.

Abstract : Over the last 18 months we have completed almost all of the tasks which we set for ourselves to accomplish, as enumerated below: Problem 1 An Interferometric Investigation of Terminal Double Mach Reflections in low-Gamma Gases - isobutane (C4H10) and sulfurhexafluoride (SF6). This problem has been completed and resulted in the presentation of the paper. A Resolution of the von Neumann Paradox , by J. T. Urbanowicz and I. I. Glass at the 8th International Mach Reflection Symposium, held at UTIAS, during July 12-15, 1988. Problem 2 An Interferometric Investigation of the Diffraction of a Planar Shock Wave over a Circular Cylinder in Air. This problem has been completed and resulted in the presentation of the paper with the same title by J. Kaca and I. I. Glass at the 8th International Mach Reflection Symposium, held at UTIAS, during July 12-15, 1988. Problem 3 An Interferometric Investigation of the Diffraction of Planar Shock Waves. Problem 4 Completion of Instrumentation, Calibration and Shakedown of the Shock-Tube. Problem 5 Normal Shock-Wave Structure in a Dusty-Air Shock- Tube. Problem 6 The Pitot Tube in a Dusty-Air Shock-Tube. Problem 7 Laminar Sidewall Boundary Layer Induced by a Moving Shock Wave in a Dusty-Air Shock-Tube. Problem 8 Flat Plate Boundary Layer Induced by a Moving Shock Wave in a Dusty-Air Shock-Tube.
