Book Description
The IUTAM Symposium on Three-dimensional Turbulent Boundary Layers was suggested by the Gesellschaft für Angewandte Mathe­ matik (GAMM) and sponsored by the International Union of theor­ etical and Applied Mechanics. The symposium was organized by H.H. Fernholz (Hermann-Föttinger-Institut für Thermo- und Fluiddynamik der Technischen Universität Berlin) and E. Krause (Aerodynamisches Institut der RWTH Aachen). After two success­ ful Euromech Colloquia on the same topic in Berlin 1972 and Trondheim 1975 the organizers felt that another meeting should be convened, this time with participants from inside and out­ side Europe. The aim of the symposium has been to bring together scientists who are actively engaged in boundary layer research, both ex­ perimental and theoretical. The scope of the meeting encompass­ ed incompressible and compressible three-dimensional turbulent boundary layers. Special emphasis was laid on economical cal­ culation methods, on measurements of fluctuating quantities and on measuring techniques designed for and applied success­ fully to three-dimensional boundary layers. From among thirty-four papers submitted for presentation, twenty­ six contributions of twenty-five minutes each were selected by the European mernbers of the Scientific Committee. Furthermore there were four invited lectures of forty-five minutes. Short discussions were held directly after each presentation with a long discussion period at the end of each day. The final dis­ cussion on the last day of the symposium was recorded on tape and is presented in a slightly shortened version as the last contribution in this volume.

Book Description
A numerical method of calculating the laminar boundary layer on any three-dimensional surface in steady compressible flow is presented. This method can be applied readily on an automatic digital computer with any desired accuracy. It is valid at and near the usual singular points and lines of a surface as well as elsewhere. A principle clarifying various aspects of three-dimensional flow also is given. (Author).

Book Description
A method is presented for computing three-dimensional, time-dependent, compressible, turbulent boundary layers in nonorthogonal curvilinear coordinates. An integral method is employed in the interest of computational speed and because the three-dimensional method is an extension of an existing two-dimensional method. After presenting a detailed derivation of the integral form of the boundary-layer equations, the necessary auxiliary relations are given along with the relationships between integral lengths expressed in streamline and nonorthogonal coordinates. A time dependent approach is used to account for time accuracy (if desired) and to provide a method that is compatible with the surface grid used by an inviscid solver for use in viscous-inviscid interaction calculations. The equations are solved using a Runge-Kutta scheme with local time stepping to accelerate convergence. Stability and convergence of the numerical scheme are examined for various space differences compared with measurements and with computations of previous investigators.

Book Description
The report concerns the calculation of coupled skin friction and heat transfer in compressible, turbulent, three-dimensional boundary layers. It presents an integral method of solution which assumes law-of-the-wall velocity and temperature correlations and results in three, coupled partial differential equations whose dependent variables are the dimensionless components of local skin friction and the dimensionless local heat transfer. The method allows for the specification of arbitrary distributions of free stream pressure, Mach number and wall temperature. The present theory is capable of handling problems of extreme complexity with moderate difficulty. (Modified author abstract).
