Two numerical methods for three-dimensional boundary layers

Abstract
Two finite-difference procedures are described for the computation of steady, three-dimensional boundary layers in ducts. In addition to the velocity components, one method uses pressure as the fourth dependent variable, while the other uses vorticity. Both methods take full account of shear stresses and heat fluxes on planes aligned with the main flow direction, and allow for non-uniform transport and thermodynamic properties. There is no restriction as to boundary conditions.
