Predictive Modeling of Local Film-Cooling Flow on a Turbine Rotor Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the turbine section of a modern gas turbine engine, components exposed to the main gas path flow rely on cooling air to maintain hardware durability targets. Therefore, monitoring turbine cooling flow is essential to ...
Evaluating the Influence of Rotor-Casing Eccentricity on Turbine Efficiency Including Time-Resolved Flow Field Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The clearance that exists between the casing and turbine blade tips is one of the key drivers of efficiency in gas turbine engines. For this reason, engine manufacturers utilize precise manufacturing techniques and may use ...
Characterizing Flow Instabilities During Transient Events in the Turbine Rim Seal Cavity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas turbine engine design requires considerations not only for long-term steady operation but also for critical transient events. Aircraft engines undergo significant stress during takeoff and landing, while power generation ...
Evaluating the Effects of Transient Purge Flow on Stator-Rotor Seal Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As modern engine designs target higher efficiencies through increased turbine inlet temperatures, critical turbine components are at increased risk of damage from conditions exceeding material melting temperatures. In ...
Correlating Time-Resolved Pressure Measurements With Rim Sealing Effectiveness for Real-Time Turbine Health Monitoring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Purge flow is bled from the upstream compressor and supplied to the under-platform region to prevent hot main gas path ingress that damages vulnerable under-platform hardware components. A majority of turbine rim seal ...
