Effect of thermal barrier coating on the thermal characteristic of turbine blade and its geometric optimization

Abstract
Thermal barrier coatings (TBC) and cooling structures are critical factors influencing the performance of aviation turbine blades. In order to investigate the effects of TBC and different cooling structures on the operating temperature and thermal stress of turbine blades, this study establishes a three-dimensional fluid-thermal-solid coupling model for aviation turbine blades. Based on this model, the study analyzes the effect of TBC thicknesses and different design architectures on the blade thermal characters, including temperature distribution and thermal stress analysis. Stress analysis is also conducted on blades with the best heat dissipation performance. The results indicate that as the thickness of the TBC increases, the blade temperature gradually decreases. Cooling channels effectively reduce turbine blade temperatures. It is also found that a reasonable increase in film cooling holes can further reduce blade temperatures. The thermal stress on the blade gradually decreases along the blade height, with the high-stress regions primarily concentrated at the junction between the blade body and the margin plate. The maximum stress is observed at the trailing edge. The conclusions of this study can provide valuable guidance for the design of aviation turbine blades with better thermal performance.
