This book was released on 1978 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laminar three-dimensional boundary layer on a body of revolution at incidence is investigated using two methods. In the first, the standard equations are solved numerically using the Keller box scheme. The second method solves a set of equations, which contain the standard equations, derived from the assumption that crossflow gradients may be important. Since these equations are elliptic in the crossflow plane, an ADI procedure is used for their solution. In regions where there is no crossflow reversal, both methods yield the same results. However, differences appear in regions where the crossflow is not unidirectional. Reasons for this discrepancy are discussed and the relative merits of each procedure identified. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional thin boundary-layer equations for laminar and turbulent flows are solved by two different numerical schemes. The methods are applied to the flow over bodies of revolution at incidence and the results are compared with the available experimental data in order to study the range of validity of the classical boundary-layer approximations in regions of increasing circumferential gradients and flow reversal associated with the early stages of a free-vortex type of separation. Comparison with the DFVLR 6:1 spheroid data of Meier et al and the 4:1 combination-body data of Ramaprian, Patel and Choi indicate that the methods perform well in regions where the boundary layer remains thin but the predictions deteriorate as the boundary layer thickens. The results point out the need for the development of methods of handle thick boundary layers and viscous-inviscid interactions. (Author).

Download or read book Three-Dimensional Laminar Boundary Layer Over Body of Revolution at Incidence. Part VI. General Methods and Results of the Case of High Incidence written by K. C. Wang and published by . This book was released on 1973 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents general methods for calculating three-dimensional laminar boundary layers over inclined blunt bodies (not necessarily bodies of revolution). Complete incompressible results for a prolate spheroid at 30 degrees incidence are presented, and the computational procedures are described. The rule of the zone of dependence was observed. The results display for the first time the boundary layer structure over a non-spherical and non-conical blunt body in all details, and confirm the open-type of separation proposed earlier. (Author).

Download or read book Three-Dimensional Laminar Boundary Layer Over Body of Revolution at Incidence. Part IX. Difference Method and Documentation of Program 'BLIND3'. written by K. C. Wang and published by . This book was released on 1975 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report documents the program 'BLIND3' and its associated difference methods. BLIND3 stands for Boundary Layer in 3 Dimensions. This program is for calculating genuine three-dimensional, incompressible, laminar boundary layer over a blunt-body at incidence. The whole calculation consists of the following five parts: inviscid calculations from known inviscid solution, stagnation-point boundary layer, symmetry-plane boundary layer, nose region boundary layer, and main body boundary layer. This program has been written in FORTRAN 5 language, and used for a UNIVAC 1108 computer in batch mode and under Exec. 8 system. It has been employed to obtain complete boundary layer solutions for a prolate spheroid at low and high incidences.

This book was released on 1977 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface streamline patterns on three bodies of revolution, namely a spheroid, a low-drag body and a hemisphere-hemispheroid combination body, have been examined at several angles of attack. Most of the tests were performed at low Reynolds numbers in a hydraulic flume using colored dye to make the surface flow visible. A limited number of experiments was also carried out in a wind tunnel, using wool tufts, to study the influence of Reynolds number and turbulent separation. The study has verified some of the important qualitative features of three-dimensional separation criteria proposed earlier by Maskell, Lighthill, Wang and others. The observed locations of laminar separation lines on a spheroid at various incidences have been compared with the numerical boundary-layer solutions of Wang, and it is suggested that the quantitative differences may be attributed to the significant viscous-inviscid interaction, especially at large incidences.

This book was released on 1982 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation is carried out into the properties of a nonsimiliar boundary layer on a cone at incidence with special reference to the flow near the leeside line of symmetry. The nonsimilarity is induced by allowing suction near the vertex of the cone and the external velocity is given by supersonic inviscid theory. The principal new results of the theory may be expressed in terms of a parameter -k, which is approximately equivalent to the angle of attack of the cone. Three ranges of k have been identified. For small negative values of k, the three-dimensional boundary layer on the cone is smooth everywhere and, once the suction is removed, rapidly approaches a semi-similarity form as the distance from the vertex increases. For more negative values of k the boundary layer is not smooth near the leeside of the cone but can be computed everywhere. The nature of this singularity is partially explained in terms of a collision phenomenon. If k decreases further, separation occurs in computations from the windward side of the cone. The solution develops a singularity along this line provided sufficient care is taken in the calculations. An apparent nonuniqueness in the solution prevents integration from the leeside over the remainder of the region of accessibility.

Three-Dimensional Laminar Boundary Layers and the OK of Accessibility written by Tuncer Cebeci and published by . This book was released on 1980 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation is carried out into the structure of the laminar boundary layer originating from the forward stagnation point of a prolate spheroid at incidence in a uniform stream, assuming that the external velocity distribution is given by attached potential theory. The principal new results of the study are: (1) A new transformation of the body coordinates is devised which facilitates the computation of the solution near the nose, (2) Two variations of the standard box method of solving the equations are devised to enable solutions to be computed in regions of cross-flow reversal, (3) Whereas in two dimensional flows the effect of the boundary layer approaching separation on the external flow may be represented by a blowing velocity, in the present study we find that this is only true near the windward line of symmetry, (4) The boundary layer over the whole of the spheroid cannot be computed in an integration from the forward stagnation point. (5) For alpha> or = 15 deg the accessible region on the leeward side of the ok is largely determined by the external streamline through the ok.

Download or read book Three-Dimensional Turbulent Boundary Layer on a Body of Revolution at Incidence written by V. C. Patel and published by . This book was released on 1983 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental and theoretical study of three-dimensional boundary layers on bodies of revolution at incidence was conducted during the period May 1980-July 1983. This final report summarizes the technical accomplishments. Reference is made to previous reports and papers resulting from the study and some recent experimental results on the boundary layer in the plane of symmetry and the vortex formation region are presented. One of the primary objectives of this study was to develop instrumentation for the measurement of the mean flow and the Reynolds stresses in three-dimensional turbulent boundary layers, and to use these to supplement the mean-flow measurements made earlier by Ramaprian, Patel and Choi on the combination body at an incidence of 15 degrees.

This book was released on 1971 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The previously investigated three-dimensional boundary layer near the plane of symmetry of an inclined spheroid is extended along three directions: wider range of solutions, explanations to questions left unanswered before, and comparisons with experiments. Extended solutions provide more complete trends for incidences from zero to 90 degrees and for thickness ratios ranging from unity for a sphere to nearly zero for a long inclined sylinder. Among these trends is how the separation changes from one type to another and then back again with increasing incidence. Explanations are given for a number of unconventional features; included here is why the lateral derivative of the cross velocity profile reverses. Agreement with Wilson's recent experiments (designed specifically for partial check of the results obtained earlier) enhances the significance of the investigation undertaken.

This book was released on 1973 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents results of exact, full three-dimensional solutions of the incompressible laminar boundary layer over a prolate spheroid at an extremely high incidence. In contrast to the high incidence (30 degrees) case recently reported, this extremely high incidence (45 degrees) problem is characterized by features reflecting the predominance of the circumferential flow over the meridional flow and, more importantly, by a closed, rather than an open, separation pattern. These features include much larger circumferential skin friction than meridional skin friction and that the limiting streamlines are more closely oriented along the parallels. (Author).
