This book was released on 1989 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This AGARDograph presents a wide range of recent work on compressible turbulent boundary layers. Special attention has been paid to flows with rapid changes in pressure including flows with shock waves, curved walls and expansions. Recent developments in the theory and experimental practice for these flows are presented. The application of rapid distortion theory to flows traversing expansion and shock waves is reviewed. This is followed by an account of experiments in progress aimed at elucidating the large scale structures present in supersonic boundary layers. The current status of the techniques of Laser-Doppler and Hot Wire anemometry in supersonic flow is discussed, and a new interferometric technique for the determination of wall-stress is described. The use of small pressure transducers to deduce information abut the structure of zero pressure-gradient and severly perturbed boundary layers is investigated. Finally there is an extension of the review and data presentation of AGARDographs 223, 253 and 263 to cover some of the experiments dealing with rapidly distorted layers.

Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the principles and practice of hot wire anemometry for the measurement of turbulent flows. The requirements and pitfalls involved in the use of hot wire anemometers in sypersonic flows are addressed and the methods used for data acquisition and reduction are detailed. Examples of measurements obtained in AFWAL facilities are presented. Unfortunately in most flows of practical interest, local fluctuation levels exceed those for which reliable hot wire turbulence measurements can be expected. However, our recent developments in laser velocimetry facilitate the non-intrusive, linear measurement of high speed turbulent flows. Measurements of zero pressure gradient and ramp induced adverse pressure gradient flows are presented. The results emphasize the need for combined hot wire and laser velocimeter studies to determine the reliable and useful ranges of both instruments.

Adams and published by . This book was released on 1972 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical approach toward numerical calculation of the three-dimensional turbulent boundary layer on a sharp cone at incidence under supersonic and hypersonic flow conditions is presented. The theoretical model is based on implicit finite-difference integration of the governing three-dimensional turbulent boundary-layer equations in conjunction with a three-dimensional scalar eddy-viscosity model of turbulence. Comparison is made of present theory with detailed experimental measurements of the three-dimensional turbulent boundary-layer structure (velocity and temperature profiles), the surface streamline direction (obtained via an oil-flow technique) and surface heat-transfer rate.

Available in PDF, EPUB and Kindle. Book excerpt: Analysis of Turbulent Boundary Layers focuses on turbulent flows meeting the requirements for the boundary-layer or thin-shear-layer approximations. Its approach is devising relatively fundamental, and often subtle, empirical engineering correlations, which are then introduced into various forms of describing equations for final solution. After introducing the topic on turbulence, the book examines the conservation equations for compressible turbulent flows, boundary-layer equations, and general behavior of turbulent boundary layers. The latter chapters describe the CS method for calculating two-dimensional and axisymmetric laminar and turbulent boundary layers. This book will be useful to readers who have advanced knowledge in fluid mechanics, especially to engineers who study the important problems of design.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the reader to the field of compressible turbulence and compressible turbulent flows across a broad speed range through a unique complimentary treatment of both the theoretical foundations and the measurement and analysis tools currently used. For the computation of turbulent compressible flows, current methods of averaging and filtering are presented so that the reader is exposed to a consistent development of applicable equation sets for both the mean or resolved fields as well as the transport equations for the turbulent stress field. For the measurement of turbulent compressible flows, current techniques ranging from hot-wire anemometry to PIV are evaluated and limitations assessed. Characterizing dynamic features of free shear flows, including jets, mixing layers and wakes, and wall-bounded flows, including shock-turbulence and shock boundary-layer interactions, obtained from computations, experiments and simulations are discussed. Describes prediction methodologies including the Reynolds-averaged Navier Stokes (RANS) method, scale filtered methods and direct numerical simulation (DNS) Presents current measurement and data analysis techniques Discusses the linkage between experimental and computational results necessary for validation of numerical predictions Meshes the varied results of computational and experimental studies in both free and wall-bounded flows to provide an overall current view of the field

Download or read book Integral Solution of Compressible Turbulent Boundary Layers Using Improved Velocity Profiles written by David L. Whitfield and published by . This book was released on 1978 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A shear-work integral method is developed for calculating compressible turbulent boundary layers on planar or axisymmetric bodies. This method differs from other integral techniques primarily in the velocity profile and the velocity-temperature relation used. The velocity profile is an analytical expression that depends on the local values of skin friction, shape factor, and Reynolds number based on momentum thickness, thus no new parameters not already occurring in the integral equations are introduced. The velocity- temperature relation is also an analytical expression that describes the total- temperature overshoot near the outer edge of turbulent adiabatic wall boundary layers with nonunity Prandtl number and recovery factor. The method is fast, easy to use, and shown to provide good agreement with experimental data. The resulting computer code is relatively small. A computer program listing that is applicable to the calculation of impermeable, adiabatic wall, turbulent boundary layers for Mach numbers up to three is included.
