This book was released on 1974 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oscillating flow about a spiked body in a supersonic stream has been investigated in a wind tunnel at Mach 5 at free-stream unit Reynolds numbers of 2,500,000 to 20,000,000 per foot using fast-response pressure transducers, accelerometers and schlieren movie cameras. A tension-cone-type model with replaceable nosetips of two different lengths and two different surface roughnesses was used.

Available in PDF, EPUB and Kindle. Book excerpt: Results of a diffuser investigation in the continuous 12 x 12 cm on Hypersonic Tunnel No. 4 are presented. A brief introduction describes previous supersonic diffuser work. The diffuser investigated and the experimental techniques are then discussed. The results show first that air condensation has little or no effect on diffuser performance. Data on diffuser throat areas and overall pressure ratios needed to start and maintain hypersonic flow are given for a Mach number range from 5.9 to 9.6. The effect of two different throat locations and different diffuser configurations on tunnel performance is investigated. A peaked throat diffuser with 3 deg wall divergence aft of the throat was selected for a more detailed study. The pressure recovered by this optimum diffuser in the range 5.9

Available in PDF, EPUB and Kindle. Book excerpt: In order to assess the direct influence of surface roughtness upon heat transfer andits indirect effect through the shift in transition location, a series of wind tunnel tests were carried out. A fixed body shape (with one exception) with varying roughness was tested at a series of tunnel conditions and the heat transfer measured by the thin wall calorimenter method. The wind tunnel conditions and the heat transfer distribution around the models are presented in tabular form.
Download or read book Experimental Investigation of a Fin cone Interference Flow Field at Mach 5 written by Gillerlain, Jr. (Joseph D.) and published by . This book was released on 1976 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general purpose of this investigation was to study the separated flow field associated with a fin-body juncture. Specific objectives included: (a) determining the severity and extent of aerodynamic heating, (b) providing flow visualization results to illustrate the flow structure, and (c) obtaining a data base of heat-transfer and surface-pressure measurements upon which to develop future analytical relations to predict peak interference heating levels. Tests were conducted at Mach 5 over a unit Reynolds number range of 4.5 to 26 million per foot. A fin-cone model was used. The data consist of surface- pressure distributions, heat-transfer measurements using the phase-change paint technique, and schlieren and oil-flow photographs. Results are presented for several fin-cone geometries to include fin sweep and fin-cone gap. Where possible, comparisons are made with fin-flat-plate data.

This book was released on 1976 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the phase-change paint technique has evolved into an accepted diagnostic tool in high-speed wind-tunnel testing. This report documents use of the method at the Naval Surface Weapons Center, White Oak Laboratory, to study aerodynamic interference heating on fin-body configurations. Various aspects of both the underlying theory and the experimental method are enumerated based on experience and on information from other researchers. Analytic relationships are presented which indicate how uncertainties in the various input parameters affect the uncertainty in the heat-transfer coefficient. Advantages and disadvantages of the phase-change paint method are discussed.
