Flow characterization of microscale effusion and transpiration air cooling on single blade
Case Studies in Thermal Engineering, 2022 Micro cooling has drawn attention as the next-generation cooling technique that is better than film cooling for a high-temperature turbine blade. Not to reduce the gas turbine efficiency while having high blade cooling effectiveness, it recommends that ...

Experimental Study of Impingement Effusion-Cooled Double-Wall Combustor Liners: Thermal Analysis
Energies, 2021 A new experimental study is presented for a combustor with a double-wall cooling design. The inner wall at the hot gas side features effusion cooling with 7-7-7 laidback fan-shaped holes, and the outer wall at the cold side features an impingement hole ...

Deposition Characteristics of Particles with Different Diameters in an Impingement-Effusion Structure with a Double-Wall Blade [PDF]
Journal of Applied Fluid Mechanics, 2023 Ingestion and deposition of fine particles on the surface of the coolant passage degrade the blade’s cooling performance. This paper proposes a deposition model to investigate the complex deposition characteristics of fine particles during repeated ...
