Mechanisms of Loss Surge and Evolution in a Highly Loaded Transonic Turbine Nozzle Guide Vane: A Novel Loss Decomposition Method via Micro-Streamtube Energy Analysis
Highly loaded turbines can effectively reduce the number of turbine stages and enhance the engine thrust-to-weight ratio by increasing the aerodynamic loading per stage. However, the associated loss mechanisms are highly complex and involve multiple interacting sources. Further performance improvements will be severe...
