RISAerodynamics and Heat Transfer Inside a Gas Turbine Mid-Passage Gap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas turbine blades and vanes are typically manufactured with small clearances between adjacent vane and blade platforms, termed the mid-passage gap. The mid-passage gap reduces turbine efficiency and causes significant ...
The Hybrid Pathway to Flexible Power Turbines, Part I: Novel Autoencoder Methods for the Automated Optimization of Thermal Probes and Fast Sparse Data Reconstruction, Enabling Real-Time Thermal Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The global drive toward renewable energy is imposing challenging operating requirements on power turbines. Flexible load-leveling applications must accept more frequent and demanding start-stop cycles. Full transient ...
