NUMERICAL-SIMULATION OF CONJUGATE HEAT-TRANSFER UNDER CONDITIONS OF FLOW AROUND GAS-TURBINE BLADES

The problem of heat transfer on the surface of a blade is solved numerically in the approximation of the boundary layer with the two-layer algebraic model of turbulence. The theoretical and experimental data are compared to analyze the various aspects of applying the latter model to the calculation of heat transfer on profile sides. The proposed approaches are used for numerical simulation of the thermal state of a sheathed blade structure with convective internal cooling.
