Large Eddy Simulation of Externally Induced Ingress about an Axial Seal by Stator Vanes
Energies, 2023 Turbine inlet temperatures in advanced gas turbines could be as high as 2000 °C. To prevent ingress of this hot gas into the wheelspace between the stator and rotor disks, whose metals can only handle temperatures up to 850 °C, rim seals and sealing ...
