This book was released on 1975 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is concerned with viscous/inviscid interactions in two and quasi-three-dimensional supersonic flows with separation. Interaction effects are modeled through the so called 'displacement body concept', wherein it is assumed that the inviscid flow 'sees' an effective body obtained by adding the displacement thickness to the original surface. The governing equations in the viscous region are taken to be the interacting boundary-layer equations and an alternating-direction-implicit (ADI) finite difference scheme is employed to obtain their solution. This technique is applied to the quasi-three-dimensional problems resulting from flow past swept (yawed) and axisymmetric compression surfaces. Detailed distributions of surface pressure, skin friction and heat-transfer are presented for Mach numbers of 2 to 6. It is found that both cross flow and axisymmetric effects are easily accommodated in the solution technique and that the predicted results are in qualitative and quantitative agreement with available experimental data.

This book was released on 1970 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium focused on departures from the classical boundary layer theories toward shock wave-boundary layer interactions with their attendant flow separation and reattachment and toward the three-dimensional viscous interactions of practical configurations. It thus dealt with one of the key problem areas associated with high speed supersonic aircraft, lifting-reentry vehicles, and potential hypersonic cruise vehicles. Such configurations are highly three-dimensional with complex flows involving strong viscous-inviscid interactions in regions of compression such as in air breathing engine inlets, at wing-body junctions, and over control surfaces.

Book excerpt: The paper presents results of analysis and experiment bearing on three-dimensional effects in hypersonic interaction, with emphasis on a sharp-edged rectangular corner intersection aligned with the flow and a sharp-edged plate of finite span. A powerful tool for dealing with such complex problems is the 'merged-layer approximation' which obviates the need for complicated matching procedures in many instances of importance although numerical computation is required. This type of flow, in which various elements are strongly coupled and even merged, is shown to have features in common with low-speed three-dimensional boundary layers such as those along an interior corner or along the edge of a quarter-infinite plate. In the low speed cases the essential viscous-inviscid interaction coupling enters through the weak, Reynolds-number dependent, displacements of the inviscid flow which must be taken into account even to lowest order. The attendant analytics and numerics are in many respects more difficult to deal with than those of the hypersonic counterparts. (Author).

This book was released on 1980 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study has been made of transpiration cooling of typical hypersonic re-entry configurations with a primary emphasis on experimental data acquisition, although some limited analytical and numerical support studies have been undertaken. The experiments have been conducted in the hypersonic flow region, under zero and non-zero angle of attack conditions, and covering the range in Reynolds numbers required to obtain laminar, transitional, and turbulent data. Numerical and analytical studies have been performed of viscous and interacting viscous-inviscid flows with application to 3D boundary layers, wing-body configurations, and internal flow problems. In this area, the development of numerical techniques and analytical tools is of primary significance although the application of these methods to practical problems of interest has also been accomplished.

This book was released on 1968 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The solution for the steady three-dimensional inviscid flow about supersonic blunt cones at angle of attack is obtained by coupling a direct time-dependent solution for the subsonic portion of the shock layer with steady state numerical afterbody solution. An outline is given covering the coupling scheme and the use of the resulting Fortran computer code.

Available in PDF, EPUB and Kindle. Book excerpt: The viscous supersonic flow over a sharp cone at incidence is examined numerically with a coupled strongly implicit algorithm for the properties in the plane normal to the cone axis. The Navier-Stokes equations are considered in a boundary layer-like or parabolized manner and global relaxation is considered for the pressure interaction. It is shown that departure effects can be effectively eliminated by forward differencing for the axial pressure gradient. Moreover, this approximation retains the implicit free pressure interaction required for geometries where axial flow separation is possible. (Author).
