Abstract: This paper presents a new unconventional philosophy for high-pressure (HP) vane design. It is proposed that the most natural design starting point for admitting and accelerating flow with minimum loss and secondary flow ...

Abstract: Rim seals are fitted in gas turbines at the periphery of the wheelspace formed between rotor disks and their adjacent casings. These seals, also called platform overlap seals, reduce the ingress of hot gases which can limit ...

Abstract: Abstract. Gas turbine secondary air systems enable elevated turbine entry temperatures for increased cycle efficiency and work output. To prevent the ingress of hot mainstream gas into the turbine cavity, purge flow is ...
