ABSTRACT
The generalized integral transform technique (GITT) is employed in the hybrid numerical-analytical solution of the compressible boundary-layer equations in the streamfunction-only formulation, as written for the laminar flow of a Newtonian fluid within a parallel-plates channel. The solution methodology is applied to a mixed-convection problem and the convergence behavior of the present error-controlled solution is studied. Numerical results from this more general model are compared to the Boussinesq formulation, in an attempt to investigate the limits of this common approximation, together with critical comparisons to some literature results.
