Abstract
The exploitation of unsteady effects in turbomachinery as a way to enhance performance is a challenge that future design systems must cope with. In this work a time-accurate viscous solver was used to investigate on unsteady bladerows interaction in axial turbines. Such studies were aimed at providing physical insights into component interactions and at gaining performance benefits by introducing interaction-aware design tools. Applications of such concepts, concerning high-lift turbine flows and airfoil clocking in subsonic as well as in transonic conditions, will be presented and discussed.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
