This book was released on 1979 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work reported herein represents the third phase of a fundamental study of transonic flow separation with extensive experimental measurements and some numerical Navier-Stokes solutions for high Reynolds number two-dimensional flow. The flow conditions have been extended to include low supersonic free-stream cases. The tests were performed over a Mach number range of 0.6 and 1.32 and Reynolds number range of 4 to 200 million. Simple geometrical surface and flow discontinuities of different sizes (such as ramps, rearward and forward-facing steps, cylinders, etc.) were selected to cause upstream disturbances and/or generate downstream adverse pressure gradient regions strong enough to produce local flow separation. The incipient separation angle in flow over ramp compression corner was measured. An average incipient separation angle of 22.5 degrees was confirmed, with no Reynolds number effect in the above range of free-stream flow parameters.

Book excerpt: The work reported herein represents the second phase of a fundamental study of subsonic and transonic flow separation. The detailed features of the turbulent boundary layer flow separation induced by a foward-facing step in transonic and high subsonic flow were studied. The influences of an upstream disturbance upon the downstream separation were simulated by several shallow-cavity models of different depth to length ratios. The free-stream conditions were varied over the ranges M = 0.6 to approx. 0.9 and Re/ft = 5 x 10 to 6th power to approx. 30 x 10 to the 6th power It was shown that certain upstream disturbances can produce higher separation pressure and skin friction than related to a single forward-facing step. A separation pressure correlation was established empirically from the cavity flow data. It was observed that a certain Reynolds number and depth-to-length-ratio cavity yielded a maximum separation pressure. At the same time, an increase of free-stream Mach number continuously increased the separation pressure. The flow relaxation along the cavity floor was explored by systematic measurements and analysis of surface pressures and velocity profiles. These studies revealed that the flow relaxation started from the floor and spread outward. Therefore, the lower portion of the outer layer of the shear flow contained a longer memory, carrying the influence of the upstream disturbance to the downstream separation. The law of the wall and the wake was used for the analysis of the velocity distributions and the estimation of the skin friction. It was found that the slope of the law of the wall is different for velocity profiles of different strengths of wake.

Available in PDF, EPUB and Kindle. Book excerpt: For flow over a two-dimensional ramp compression corner case, an experimental investigation to determine the incipient separation was carried out at Mach numbers between 0.55 and 0.9 and Reynolds numbers (based on undisturbed boundary layer thickness) between 350,000 and 690,000. Detailed surface pressure, pitot traversing and oil flow data were obtained for each ramp angle case. Two-dimensionality of the ramp compression corners was verified by the surface oil flow. A major finding of this study is that the incipient separation ramp angle is relatively independent of Mach number and Reynolds number within the range studied. The incipient separation ramp angle was found to be about 22.5 degrees.
