Using the developed 3D CFD model, the thermal state (full three-dimensional temperature field) of the GTE cooling blade (Fig. a) is calculated taking into account the heat exchange between the working gas, the blade body and the cooling air channels (Fig. b) in a conjugate formulation, which allows calculating the thermally stressed the state of the scapula (Fig. c).
Development of models of the thermogasdynamic state of the blades to provide the necessary parameters of the cooling system.
