ABSTRACT

Developing turbulent flow between parallel plates is analyzed, by making use of the generalized integral transform technique to obtain a hybrid numerical-analytical solution of the governing boundary layer equations for incompressible steady flow. The streamfunction-only formulation is preferred over the primitive variables one, in light of the improved convergence rates achievable, for the related eigenfunction expansions, with the former choice. Also, a well-established algebraic turbulence model is adopted for the required flow diffusivities, and numerical examples are employed to illustrate the computational performance of the proposed approach.
