Numerical Study of a Gas Turbine's Shaft Cooling

In order to investigate the heat transfer between the secondary air flow and the turbine's shaft, several computations were performed, using the CFD software Ansys CFX. Several cases were analyzed, by modifying the geometry, the material, as well as the air mass flow passing through the analyzed path. The comparison between the different results led to the selection of the best configuration, in terms of cooling performances.
