This book was released on 1970 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Initial testing and a preliminary calibration were conducted in the UMR supersonic variable Mach number axisymmetric blowdown wind tunnel facility. During initial operations problems were encountered with control valve seat failure, control valve response and stability, and automatic operation. After having brittle fracture failures with seats made of nylon, Teflon and Telfon-copper composite, a copper seat was found to perform satisfactorily with minimal valve leakage. Control valve response and stability were greatly influenced by the setting of the needle valve located between the total pressure probe and the controller. The needle valve setting was observed to depend upon the stagnation pressure, the supply pressure, and the rate at which the valve was stroked. The result of each of the various methods of automatic operation tried was a pressure overshoot, bursting bypass diaphragms. Through manual operation excellent repeatability of stagnation pressure was obtained. The tunnel calibration vats performed at a stagnation pressure of 180 psig. By means of schlieren flow visualization the free jet was found to be completely expanded at this pressure. From cone-shock angle measurements the test section Mach number was approximately 2.8. A more discreetly defined nozzle contour and improved machining and polishing techniques are needed to rid the flow field of Mach waves emanating from the nozzle. An estimate of the run time by an empirical quasi-steady isentropic analysis was found to be in good agreement with the experimentally determined value"--Abstract, leaf ii.

Available in PDF, EPUB and Kindle. Book excerpt: "The design and construction of the McGill intermittent, suckdown supersonic wind tunnel and its instrumentations are described. It operates on the pressure differential between the atmosphere and a 320 cu. ft. vacuum. storage tank. The running time for Mach number of 1 .8 is in the vicinity of twelve seconds with a test section area of approximately four sq. in.. Theoretical as well as experimental performance curves for the wind tunnel are presented. Calibrations of a Mach 1.8 axisymmetric nozzle and a Mach 1.8 two-dimensional nozzle are given in detail. The Mach number distribution compares favourably with other supersonic wind tunnels. The tunnel is being used to study supersonic flow in ducts, and problems concerning multiple shock waves and orifice experiments." --

This book was released on 1957 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Static pressure and temperature surveys were conducted in the 4.5-inch diameter, axisymmetric, intermittent-flow, supersonic wind tunnel to determine the flow characteristics. Both horizontal and vertical surveys were made at nine stations along the center line one inch apart. The static pressures were measured using Statham pressure transducers. The maximum Mach number variation was plus or minus 0.02 for the upstream part of the test section and plus or minus 0.03 for the downstream part. An axial Mach number gradient of 0.012 per inch was found. There was no evidence of a focussing conical shock wave in the core of the test section. A five-probe, shielded-thermocouple type, temperature rake measured stagnation temperatures in the test section. The maximum temperature variation across the test section was 0.66 percent of the absolute stagnation temperature. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen tremendous progress in research on cold and controlled molecular collisions, both in theory and in experiment. The advent of techniques to prepare cold and ultracold molecules and ions, to store them in optical lattices or in charged quasicristalline structures, and to use them in crossed or merged beam experiments have opened many new possibilities to study the most fundamental aspects of molecular interactions. At the same time, theoretical work has made progress in tackling these problems and accurately describing quantum effects in complex systems, and in proposing viable options to control chemical reactions at ultralow energies. Through tutorials on both the theoretical and experimental aspects of research in cold and ultracold molecular collisions, this book provides advanced undergraduate students, graduate students and researchers with the foundations needed to understand this exciting field.
