Abstract: For novel high-speed small core turbines, with tip clearance below 0.5 mm, even small blade-to-blade tip clearance variation is significant. The assessment of these complex flows is pertinent to the design of the next ...

Abstract: The tip leakage flow is known to be a substantial loss contributor. A precise local loss decomposition of the relevant laminar and turbulent terms for viscous losses and thermal losses is required to predict the impact of ...

Abstract: New compact engine architectures such as pressure gain combustion require ad hoc turbomachinery to ensure an adequate range of operation with high performance. A critical factor for supersonic turbines is to ensure the ...
