Download Two-Dimensional Turbulent Boundary Layer Separation on a Flat Plate with Ramp at Freestream Mach Numbers of 3.7 and 6.3 in Supersonic and Hypersonic Flow Book in PDF, ePub and Kindle
This investigation describes surface pressure distribution, heat transfer, and turbulent flow separation and reattachment on a flat plate with variable ramp angle at Mach numbers averaging 3.66 and 6.30. The freestream Reynold's number varied from 3.33 to 8.34 million per foot for the former case and from 5.243 million to 14.6 million per foot for the latter case. Ramp angle was varied from 0 to 35 degrees for these experiments. Stagnation temperatures averaged 849 degrees Rankine, with wall temperature assumed constant at 535 degrees Rankine for all tests. The knowledge of effective wedge angles and freestream conditions makes it possible to determine shocks so that conditions can be evaluated at all positions on the model.

Download Investigation of Laminar Boundary-layer Separation on a Flat-plate-ramp Combination with and Without Mass Removal at Mach Numbers 6, 8, and 10 Book in PDF, ePub and Kindle
An experimental investigation of laminar boundary-layer separation induced by a trailing edge ramp on a flat plate was conducted at Mach numbers of 6, 8, and 10. The tests were conducted over a range of Reynolds numbers. Longitudinal and spanwise surface pressure distributions, pitot pressure profiles, and shadowgraph pictures were used to investigate the two-dimensionality of the flow and the effects of model geometry, angle of attack, Reynolds number, ramp angle, and mass removal from the separation region. Data are presented to show that laminar, two-dimensional boundary-layer reattachment, not limited by model geometry, was obtained. These data are compared to the integral-moment theory of Lees and Reeves as modified by Klineberg. It is also shown that a separation region can be reduced or even eliminated by removing mass at the hinge line. (Author).

Download The Prediction of Turbulent Boundary-layer Separation Influenced by Blowing Book in PDF, ePub and Kindle
The report presents an analysis predicting separation of a turbulent boundary layer over a cone-flare configuration with gas injected into the boundary layer ahead of separation point. Separation location and separation lengths are compared with experimental data obtained at Mach number of 6 and a range of Reynolds numbers. At the highest Reynolds numbers the extent of separation decreases with increasing Reynolds number. When compared to separation over cylinder-flare body it is found that the extent of separation is lower for the cone-flare configuration. (Author).

In 1975 the U.S. Air Force and the Federal Republic of Germany signed a Data Exchange Agreement numbered AF-75-G-7440 entitled 'Viscous and Interacting Flow Fields.' The purpose was to exchange data in the area of boundary layer research. It includes both experimental and theoretical boundary layer research at speeds from subsonic to hypersonic Mach numbers in the presence of laminar, transitional, and turbulent boundary layers. The main effort in recent years has been on turbulent boundary layers, both attached and separated in the presence of such parameters as pressure gradients, wall temperature, surface roughness, etc. In the United States the research was conducted in various Department of Defense, NASA, aircraft corporations, and various university laboratories. In the Federal Republic of Germany it was carried out within the various DFVLR, industrial, and university research centers.
