Summary

Gas turbine blades operate under extreme temperatures exceeding material limits. Advanced cooling research is critical to prevent thermal failure, extend component lifespans, and elevate Turbine Entry Temperature (TET) to maximize efficiency, thereby reducing fuel consumption.

This special issue focuses on innovative blade cooling technologies, film cooling optimization, the thermal performance of rotating flows, and novel cooling measures to elevate heat transfer efficacy and enhance component reliability.

The special issue includes, but is not limited to, the following themes:

* Film Cooling Optimization: Advanced hole geometries, anti-vortex designs, and trench-hole configurations.

* Internal Cooling Innovations: Novel impingement arrangement, rib turbulators, pin-fin arrays, dimples, and lattice structures.

* Novel Cooling Measures: Transpiration cooling, effusive cooling, and phase-change thermal management systems.

* Additive Manufacturing for Cooling: Design, production, and thermal testing of 3D-printed complex cooling channels.

* Thermal Performance of Rotating Flows: Experimental and numerical studies on rotation effects, buoyancy, and Coriolis forces.

* Aerodynamic-Thermal Coupling: Interaction between cooling jet ejection, mainstream flow, and aerodynamic loss.

* Unsteady and Wake Effects: Impact of stator-rotor interactions, shock waves, and free-stream turbulence on cooling efficacy.

* High-Fidelity Numerical Simulations: LES, DNS, and advanced RANS modeling for complex blade cooling flows.

* AI and Machine Learning Application: Data-driven optimization, surrogate modeling, and predictive maintenance for blade thermal management.
