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.

Download or read book Turbulent Boundary Layer Solution for Two dimensional Compressible Flow Using Mixing Length and K epsilon Turbulence Models written by M. Khalid and published by . This book was released on 1990 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuity, momentum and energy equations for two-dimensional compressible turbulent boundary layers are solved using the k-epsilon turbulence model and the extended mixing length approach to calculate the shear stress terms. The finite difference equations are set up applying Keller's box scheme and the resulting tridiagonal matrix system is solved by the block elimination method. Newton's iteration procedure is used to converge the solution. Results obtained from computations showed only a slight difference between the two methods. Both methods showed satisfactory agreement with experimental data for test cases.

This book was released on 1970 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computational method for turbulent boundary layers in an incompressible two-dimensional flow was formulated. The governing differential equations for the mean flow are solved by an implicit finite differential equations for the mean flow are solved by an implicit finite difference method. The Reynolds shear stress is correlated by Prandtl's mixing length concept. Four models of correlation for the mixing length are studied and prediction based on these models is assessed by comparison with several sets of experimental data. It is found that models correlated only to local mean flow cannot adjust themselves to the proper turbulent state for highly non-equilibrium flow. If the turbulent state is considered explicitly by computing the mixing length from the turbulent energy equation, the results show excellent agreement with experimental data. This model is thus recommended for practical uses. (Author).

This book was released on 1980 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a discussion of mean flow profile data for compressible boundary layers. In AGARDograph 223, (Fernholz and Finley, 1977) the predecessor of this volume, data were presented for nominally two-dimensional flows for which mean flow profile data were available in tabular form. Data for 59 experimental boundary layer studies were given, with a brief introduction. Comment and discussion were reserved for this volume, AGARDograph 253. Suitable cross-references are given to relate the discussion in this volume to the earlier publication. The commentary in this volume includes discussion of the theroetical basis for interpretation of measurements, concepts from low-speed studies, interpretation of mean flow data with and without pressure gradient. The causes of normal pressure gradients are described, so as to allow an estimation of their magnitude, and their influence on boundary layer scale lengths. A third volume is planned in this series, which will include additional data, some of which is discussed here. This work was sponsored by the Fluid Dynamics Panel of AGARD. (Author).

Harris and published by . This book was released on 1971 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical method for solving the equations for laminar, transitional, and turbulent compressible boundary layers for either planar or axisymmetric flows is presented. The fully developed turbulent region is treated by replacing the Reynolds stress terms with an eddy viscosity model. The mean properties of the transitional boundary layer are calculated by multiplying the eddy viscosity by an intermittency function based on the statistical production and growth of the turbulent spots. A specifiable turbulent Prandtl number relates the turbulent flux of heat to the eddy viscosity. A three-point implicit finite-difference scheme is used to solve the system of equations. The momentum and energy equations are solved simultaneously without iteration. Numerous test cases are compared with experimental data for supersonic and hypersonic flows; these cases include flows with both favorable and mildly unfavorable pressure gradient histories, mass flux at the wall, and traverse curvature.

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.
