Two-dimensional laminar compressible boundary-layer programme for a perfect gas

Abstract

A computer programme has been written to solve the steady laminar two-dimensional boundary-layer equations for a perfect gas at given wall temperature, without wall suction. The programme solves the equations at a blunt stagnation point and then solves the equations downstream. Versions for Mercury and Atlas are available. The Atlas programme will permit use of linear or Sutherland viscosity laws. In an Appendix directions are given for setting up problems for solution ; the inviscid edge velocity and wall enthalpy, as functions of downstream arclength along the body, are at the programmer's disposal. It appears possible to obtain results correct to at least three significant figures, usually more not too near separation.
