On a class of non-similar solutions of compressible boundary layer equations

摘要: Laminar boundary layer equations for a two-dimensional steady compressible flow are first transformed from the physical plane to Illingworth-Stewartson plane. The stream function and similarity variable employed in study of similar solutions are, then, suitably modified by introduction new which carries effect pressure distribution frictionless external is termed quasi-similarity transformation. obtained class non-similar flows. Transforming back plane, separation points calculated both adiabatic isothermal walls respectively. results, wherever possible, compared with known analytical full scale numerical solutions. It found that present method gives quick results reasonable degree accuracy.
