Download or read book A Survey of Transition Research at AEDC written by and published by . This book was released on 1977 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a survey of experimental research on transition Reynolds numbers conducted in a large number of ground test facilities. Facilities surveyed included primary wind tunnels used for aerodynamic testing at subsonic, transonic, supersonic, and hypersonic conditions. Measurements have been made on cones and planar bodies, flat plates and hollow cylinders. This report traces the work using cones, which has been more extensive. The primary motivation for this research spanning nearly 20 years has been to verify the adequacy of the facilities to simulate flight conditions. This necessarily entailed the study of free-stream disturbances in wind tunnels and the role these disturbances play in altering transition Reynolds number which must be considered when scaling Reynolds-number-sensitive data. Results presented include current experimental efforts as recent as September 1976. In addition to the cited references, a bibliography of relevant publications from AEDC has been included.

Boudreau and published by . This book was released on 1978 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research directed toward establishing criteria for distributed roughness-type boundary-layer trips on blunt-slender cones has been conducted in the AEDC/VKF at Mach numbers from 8 to 13. Results indicate that distributed roughness trips are superior to spherical-type trips in that equally effective distributed roughness trips are one-fifth as high and produce substantially smaller flow-field disturbances. Criteria are defined for optimum utilization of distributed roughness trips.

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)

This book was released on 1996 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The location of the stability region between the laminar and turbulent flow is of great importance in the design of high speed missiles and aircraft's. Heat transfer and skin friction vary greatly between laminar and turbulent, therefore, transition location is indispensable for predicting vehicle performance. The boundary layer stability of a sharp, 7-degree half angle cone with freestream Mach numbers of 6 and 8 was numerically investigated using linear stability theory computer program. Results were compared with wind tunnel tests results obtained at the AEDC Von Karman Hypersonic Tunnel B. Measured and computed frequencies agree well, indicating that linear stability theory properly describes the processes leading to transition at the AEDC Tunnel B.
