Cover Story: The current European regulations thrust original equipment manufacturers toward the design of new components for the life-time extension of gas turbines, characterized by increased thermodynamic performance and by reduced pollutant emissions to match the 2050 single-digit goal. The present work exploits a conjugate heat transfer approach to investigate into different feeding geometries for the internal cooling channels of a turbine blade using computational fluid dynamics. The impact of each configuration on coolant distribution, blade metal temperature, and tip leakage flows is jointly studied by Politecnico di Torino and EthosEnergy Group S.p.A. to detect a design solution for the secondary air systems for improved overall blade performance.
