A procedure for the calculation of boundary layers in flow symmetry planes

The foundations are given for an exact method for the calculation of quasi two dimensional boundary layers in symmetrical planes of flows about bodies. The boundary layer can be incompressible or compressible, laminar or turbulent (mixing-length model of R. Michel). The two dimensional and the axisymmetric case are included. Longitudinal and transverse curvature of the contour can be taken into account; at the wall blowing or suction may occur, and temperature or temperature gradient (heat transfer) can be observed. The governing equations are solved by means of a finite difference method. A sample calculation is discussed.
