Effects of thermal barrier coating thickness and surface roughness on cooling performance sensitivity of a turbine blade

Case Studies in Thermal Engineering, 2023
In this study, the conjugate heat transfer method is used to research the impact of the thermal barrier coating thickness (0–300 μm) and surface roughness (Ra = 0–30 μm) on the cooling characteristics of the high-pressure turbine blade.

Effect of the Hot Streak on the Overall Cooling Performance of a Coated Rotor Blade

Energies, 2022
The influence of the HS (hot streak) and unsteady wake on the overall cooling performance of a rotor blade was studied in this paper. The results show that: (1) Both the magnitude and temperature of the HS gradually drops down as it passes downstream of ...
