Available in PDF, EPUB and Kindle. Book excerpt: An investigation of five computer programs which calculate skin friction and boundary-layer integral properties in two-dimensional, turbulent, transonic flow was conducted. The five programs were of varying complexity and consisted of four boundary-layer-type methods with turbulence modeling varying from algebraic eddy viscosity models to a two-equation of turbulence model, and one mean flow compressible Navier-Stokes technique with algebraic turbulence modeling. The quality of the computed results was judged by comparison with available experimental data. For the data considered (which were nonseparated, two-dimensional, transonic, adiabatic wall data), the most accurate calculations of skin friction were provided by an integral boundary-layer method and a finite difference boundary-layer method, both with algebraic turbulence modeling.

Available in PDF, EPUB and Kindle. Book excerpt: Beginning with a description of turbulence, its various manifestations, and a brief history of study, this text also incorporates modern perspectives on turbulence. The text also covers such topics as intermittency and the resultant conditional sampling and averaging of turbulent flows, the role of large scale computation of the fundamental equations of fluid mechanics in providing information on variables, and asymptotic methods which are used to expose important features of turbulent flows. Meaningful exercises are included in every section.
Download or read book A Simple New Analysis of Compressible Turbulent Two Dimensional Skin Friction Under Arbitrary Conditions written by F. M. White and published by . This book was released on 1971 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new approach is proposed for analyzing the compressible turbulent boundary layer with arbitrary pressure gradient. The new theory generalizes an incompressible study to account for variations in wall temperature and free- stream Mach number and temperature. By properly handling the law-of-the-wall in the integration of momentum and continuity across the boundary layer, one may obtain a single ordinary differential equation for skin friction devoid of integral thicknesses and shape factors. The new differential equation is analyzed for various cases. For flat plate flow, a new relation is derived which is accurate for adiabatic flow and reasonably good for flow with heat transfer. For flow with strong adverse and favorable pressure gradients, the new theory is in good agreement with experiment. The new theory also contains an explicitly criterion for boundary layer flow separation.
Download or read book Prediction of Turbulent Skin Friction for Two dimensional Rib type Surface Roughness Using a Discrete Element Approach written by Robert P. Taylor and published by . This book was released on 1985 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discrete element model for turbulent flow over two-dimensional rib-type roughness is developed and validated. Surface roughness blockage effects and form drag are included as a constituent part of the differential equations. Separation and reattachment of the flow over rib roughness are identified as the dominant flow phenomena, and models are developed which incorporate the separated region geometry into the blockage. The form drag model is based on the pressure difference between the windward and leeward forces of the roughness. Predictions are compared with a variety of data sets. These comparisons indicate that the discrete element approach can be successfully applied for rib-type roughness. However, the model has a more narrow range of application for different surface geometries than the very broad range which has previously been demonstrated for three-dimensional, distributed roughness. Keywords: Two-dimensional roughness; Rib roughness; Boundary layer.
Download or read book Analysis of Turbulent Boundary Layers written by Tuncer Cebeci and published by Elsevier. This book was released on 2012-12-02 with total page 423 pages. 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: The report outlines the details for engineering use of White's two- dimensional theory of turbulent skin friction under arbitrary compressible flow conditions. The new method is not only simple but accurate. It is recommended for general use by engineering designers. The method concerns skin friction only. The report presents methods for hand or digital computer computation. Several examples are presented.
