Compressible boundary layers: An example of an efficient solution technique
Abstract
The solution of two dimensional and axisymmetric boundary layers by finite difference schemes is introduced. A method based on a combination of the generalized Crank-Nicholson and box schemes is presented and applied to boundary layer flows. The technique can be extended to the computation of wakes and jets. Laminar flows are treated, but the conclusions can be applied to the turbulent case, providing the equations are written formally in laminar form. The boundary layer equations are presented in tensorial notation to take into account curvature effects. The general equations are specialized for steady two dimensional and axisymmetric flows. A method for the solution of compressible two dimensional and axisymmetric boundary layer flows on a wall with modest curvature is outlined. Information concerning three dimensional boundary layers is presented.
