Book Synopsis Boundary-layer Transition Correlation on a Slender Cone in Wind Tunnels and Flight for Indications of Flow Quality by : N. Sam Dougherty
Download or read book Boundary-layer Transition Correlation on a Slender Cone in Wind Tunnels and Flight for Indications of Flow Quality written by N. Sam Dougherty and published by . This book was released on 1982 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boundary-layer transition location measurements were made on a 10-deg sharp cone in 23 wind tunnels in the United States and Europe and in flight. The data were acquired at subsonic, transonic, and supersonic Mach numbers over a range of unit Reynolds numbers in an effort to obtain an improved understanding of the effect of wind tunnel flow quality on transition location. The data indicate that the transition mechanism in both wind tunnels and flight is associated with the formation of Tollmien-Schlichting waves in the laminar boundary layer. However, the location of the end of transition was found to be primarily a function of the noise under the laminar boundary of the cone surface and, within + or - 20 percent, independent of Mach number and unit Reynolds number.

Book Synopsis Effects of Wall Cooling and Leading-edge Blunting on Ramp-induced, Laminar Flow Separations at Mach Numbers from 3 Through 6 by : J. Don Gray
Download or read book Effects of Wall Cooling and Leading-edge Blunting on Ramp-induced, Laminar Flow Separations at Mach Numbers from 3 Through 6 written by J. Don Gray and published by . This book was released on 1972 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of wall cooling and nose bluntness on laminar and transitional reattaching flows induced by a 9.5-degree ramp were investigated at Mach numbers from 3 through 6 measuring the longitudinal surface pressure and heat-transfer rate distributions, as well as the flow-field pressures, at several longitudinal stations. Reynolds number based on flat-plate length was varied from 0.25 to 1.0 million. The trend in the change in interaction length with Reynolds number increase indicated laminar reattachment at all test Reynolds numbers at M = 6 and transitional at the two higher Reynolds numbers at M = 3.

Book Synopsis Heat-transfer and Flow-field Tests of the McDonnell Douglas-Martin Marietta Space Shuttle Configurations by : Richard K. Matthews
Download or read book Heat-transfer and Flow-field Tests of the McDonnell Douglas-Martin Marietta Space Shuttle Configurations written by Richard K. Matthews and published by . This book was released on 1973 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerothermodynamic tests of Phase B space shuttle configurations proposed by McDonnell Douglas--Martin Marietta were conducted at Mach numbers 8 and 10.5. Test conditions provided both Mach number and Reynolds number simulation for typical ascent and reentry trajectories. This report provides a comprehensive analysis of the major test results and also presents data comparisons with theoretical calculations. Specific areas covered are ascent heating and shock interference, booster reentry heating and flow fields, and orbiter reentry analysis which includes leeside heating, windward shock angles and flow fields, windward surface heating, and boundary-layer transition.

Book Synopsis Influence of Wind Tunnel Noise on the Location of Boundary-layer Transition on a Slender Cone at Mach Numbers from 0.2 to 5.5 by : N. Sam Dougherty (Jr.)
Download or read book Influence of Wind Tunnel Noise on the Location of Boundary-layer Transition on a Slender Cone at Mach Numbers from 0.2 to 5.5 written by N. Sam Dougherty (Jr.) and published by . This book was released on 1980 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to investigate the effects of wind tunnel test section noise on the location of boundary-layer transition. The study was carried out by conducting experiments on a slender, highly polished cone with an included angle of 10 deg. Wind tunnel test section noise was measured by microphones flush-mounted on the cone surface. In most of the experiments, boundary-layer transition was measured with a surface-mounted, traversing pitot pressure probe. The experiments were conducted in 23 different subsonic, transonic, and supersonic wind tunnels over a Mach number range from 0.2 to 5.5 and a unit Reynolds number range from 1.0 to 7.0 million per foot, the bulk of the data being obtained between 2.0 and 4.0 million per foot. The results show an influence of wind tunnel noise on boundary-layer transition for most of the wind tunnels. (Author)
