Using modern CAD-embedded CFD code for numerical simulation
of heat transfer in vanes and blades

This paper presents the results of CAD-Embedded, CFD software FloEFD for evaluation of the thermal and temperature conditions of vanes and blades. The FloEFD approach is based on two main principles: direct use of native CAD as the source of geometry information; and synergy of full 3D CFD modeling, combined with simpler engineering methods in cases where the mesh resolution is insufficient for a full 3D simulation.

To validate the CFD code in the field of heat transfer in gas turbine vanes and blades three independent experiments are selected. For each case consideration is given to particular parameters of conjugate heat transfer which is computed and compared with published tests.
