Download or read book Supersonic Turbulent Flow Reattachment Downstream of a Two dimensional Backstep written by Daniel C. Reda and published by . This book was released on 1969 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical and experimental treatment of the reattachment of a two-dimensional, supersonic, turbulent separated flow is presented. A control volume in the reattachment region is analyzed, in order to predict the reattachment point location, pressure, and pressure gradient. Detailed experimental measurements were taken in the separated and reattaching flow regions, downstream of a two-dimensional backstep. A free stream approach Mach number of 3.05, and a free stream Reynolds number of 2.0 to 2.5 x 10 to the 7th power per foot were used. A continuous static pressure distribution was measured along the reattachment surface. The reattachment point was located by the orifice dam technique, the flush mounted pitot probe technique, and water injection-tracer techniques. The corner flow region was probed and lip shock effects on the mixing and reattachment regions were noted. Boundary layer profiles were taken throughout the rehabilitation region. The theoretical predictions and the experimental data exhibited close agreement. (Author).

This book was released on 1951 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical method is presented for obtaining turbulent temperature recovery factors for a thermally insulated surface in supersonic flow. The method is an extension of Squire's analysis for incompressible flow. The boundary layer velocity profile is represented by a power law and a similarity is postulated for squared-velocity the static-temperature-difference profiles.

This book was released on 1956 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some results are described of fundamental research conducted on various flow separation phenomena in two-dimensional streams. Experimental and theoretical results are described for the pressure rise across a reattachment region, and for the Reynolds number dependence of the pressure rise to a separation point. Observations are made throughout of the location of transition relative to reattachment and to separation, since this relative location turned out to be the dominant variable investigated.

Available in PDF, EPUB and Kindle. Book excerpt: Basic research programs are reported with fundamental applications to supersonic flight. The experimental studies made use of the unique capabilities of the high Reynolds number Mach 3 facility. The experimental programs concentrated on phenomena associated with incipient separation and separation of turbulent boundary layers over a large Reynolds number range. The reattachment phenomena of a shear layer was also studied in great depth.

Download or read book Analytical Nodel of Supersonic Turbulent Near wake Flows written by C. E. Peters and published by . This book was released on 1976 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical model for planar and axisymmetric, supersonic, turbulent, near-wake flows is presented. The viscous region behind the blunt base is described by the integral form of the boundary-layer equations, and the inviscid outer-flow region, including the remnant of the initial turbulent boundary layer, is computed with the rotational method of characteristics. The solution of the two regions is fully coupled. The saddle-point singularity, similar to the Crocco-Lees critical point, occurs downstream of the rear stagnation point. The base pressure is obtained by iteration of the initial conditions until the flow-field solution will pass through the singularity. Base bleed of a gas different from the outer-stream gas is included in the formulation, and provision is made to treat equilibrium chemical reactions in the viscous wake. However, an unresolved problem has been encountered in the solution of the species conservation equations. Therefore, results for only single gas flows are presented. The analytical model is shown to adequately predict the effect of free-stream Mach number and initial boundary layer on the planar base pressure. In addition, the planar flow-field structure is well predicted. Axisymmetric base pressure and flow-field structure are reasonably well predicted for free-stream Mach numbers greater than 2.0, but the turbulent transport model used yields only fair results for Mach numbers less than 1.7. The effect of base bleed on the axisymmetric base pressure is well predicted. (Author).
