Aero-thermal performance and enhanced internal cooling of unshrouded turbine blade tips

Abstract:

The tips of unshrouded, high-pressure turbine blades are prone to significantly high heat loads. The gap between the tip and over-tip casing is the root cause of undesirable over-tip leakage flow that is directly responsible for high thermal material degradation and is a major source of aerodynamic loss within a turbine. Both must be minimised for the safe working and improved performance of future gas-turbines.

A joint experimental and numerical study is presented to understand...
