Aero-thermal performance of transonic high-pressure turbine blade tips

Abstract:

This thesis presents an experimental and theoretical study of unshrouded tips on gas turbine blades with and without winglets. The goal of the winglet tip design is to reduce over-tip leakage flow. To assess the potential use of winglets, their effectiveness in reducing loss and the cooling scheme's effectiveness must be determined under engine-realistic flow conditions. An aero-thermal investigation was performed to answer these questions.

A high-speed linear cascade was commission...
