Comparison of three-dimensional turbulent boundary layer calculations with experiment

The results of several three-dimensional turbulent boundary layer calculations have been compared with each other and with experiment for a number of test cases. The calculation methods applied range from integral methods to field methods using a turbulence model based upon the Reynolds stress transport equations. The test cases comprise various...

Three-dimensional boundary layer calculations on wings, starting from the fuselage

A computational method is presented for threedimensional turbulent boundary layers. The turbulence model is a simple eddy-viscosity formulation. An hybrid difference scheme is used, which has the robustness of first order schemes and accuracy of second order schemes. The boundary layer is computed in the region of determinacy of the initial data...

Comparison of boundary layer calculations for the root section of a wing

At the workshop nine participants presented the results of their calculations for a practical test case. The test case deals with the 3D turbulent boundary layer development, including separation, on the root section of a swept wing. The employed calculation methods comprise 3D integral methods as well as field methods. A short description of...

Paper presented on the third GAMM-Conference on Numerical Methods in Fluid Mechanics, October 10 - 12, 1979, Cologne, Federal Republic of Germany.

A method for the calculation of 3D boundary layers on practical wing configurations

This paper gives a description of a calculation method for 3D turbulent and laminar boundary layers on non-developable surfaces. A simple eddy viscosity model is incorporated in the method. Special attention is given to the organization of the computations to circumvent as much as possible stepsize limitations. The method is also able to proceed...

Three-dimensional separation of an incompressible turbulent boundary layer on an infinite swept wing

An experiment is described in which a three-dimensional boundary layer flow under infinite swept wing conditions is simulated. A description is given of the development of the boundary layer in a region of an adverse pressure gradient leading to increased cross flows and finally terminating in a three-dimensional. separation. Measurements are...

Measurements in an incompressible three-dimensional turbulent boundary layer under infinite swept wing conditions and a comparison with theory

First a three-dimensional turbulent boundary-layer experiment is described. This experiment has been carried out with the specific aim to provide a test-case for calculation methods. Much attention has been paid to the design of the test set-up. An infinite swept wing flow has been simulated with good accuracy. The initially two-dimensional...
