A numerical procedure is presented for the analysis of thermal and kinematic boundary layers behavior along the blades of a gas turbine stator. Dealing with both laminar and turbulent two-dimensional compressible flows, it solves by marching integration the B.L. equations, based on Spalding’s effective viscosity model, with quite general thermal boundary conditions. It accounts for main stream turbulent level influence and, using transition criteria based upon local profiles, is able to adapt itself to any flow modification like turbulent layer laminarization, laminar to turbulent transition, separation of laminar or turbulent type.
