Abstract

A method is presented to compute the 3D compressible turbulent boundary layer on an adiabatic wall under infinite swept wing conditions. The mathematical model of turbulence is based on a generalisation of Bradshaw's 2D shear stress equation. This results in a system of 5 equations valid along 5 distinct characteristics. A brief discussion is devoted to the choice of a suitable difference scheme. A description of the FORTRAN program is given. Some results of calculations in practical cases are shown. The listing of the program and an example of input/output are included on microfiche.
