Book Description
An analysis is derived for the three-dimensional boundary-layer flow over a flat surface with a leading edge under main-flow streamlines which are translates and representable by polynomial expressions. The boundary layers are laminar snd incompressible, and the profiles of their velocity components have similarity with respect to rectangular coordinates. Solutions are obtained for main-flow streamlines representable by polynomials up to the 11th order. Flow-visualization experimental checks for the theory are provided for several flow configurations and for comparisons of the behavior of thick and thin boundary layers.

Book Description
Following an introduction to the basic physical concepts and the theoretical framework of boundary layers, discussion includes laminar boundary layers, the physics of the transition from laminar to turbulent flow, the turbulent boundary layer and its governing equations in time-averaging form, drag prediction by integral methods, turbulence modeling and differential methods, and current topics and problems in research and industry.

Book Description
This second edition of the book, Modeling and Computation of Boundary-Layer Flows^ extends the topic to include compressible flows. This implies the inclusion of the energy equation and non-constant fluid properties in the continuity and momentum equations. The necessary additions are included in new chapters, leaving the first nine chapters to serve as an introduction to incompressible flows and, therefore, as a platform for the extension. This part of the book can be used for a one semester course as described below. Improvements to the incompressible flows portion of the book include the removal of listings of computer programs and their description, and their incor poration in two CD-ROMs. A listing of the topics incorporated in the CD-ROM is provided before the index. In Chapter 7 there is a more extended discussion of initial conditions for three-dimensional flows, application of the characteristic box to a model problem and discussion of flow separation in three-dimensional laminar flows. There are also changes to Chapter 8, which now includes new sections on Tollmien-Schlichting and cross-flow instabilities and on the predic tion of transition with parabolised stability equations, and Chapter 9 provides a description of the rational behind interactive boundary-layer procedures.

Book Description
The report presents a general method for solving the laminar and turbulent boundary layer equations for swept infinite cylinders and for small cross flows. In the equations the Reynolds shear stress terms are eliminated by using an eddy viscosity concept. An efficient two-point finite-difference method used earlier by Keller and Cebeci for two dimensional flows is used to solve the governing equations. The method has been programmed on the IBM 370/165. (Author).

Book Description
This book provides a comprehensive overview of boundary layer flows, including laminar and turbulent flows. Chapters discuss such topics as the nature of transition, the effect of two-dimensional and isolated roughness on laminar flow, and progress in the design of low-drag airfoils. They also present theoretical and experimental results in boundary layer flows and discuss directions for future research.
