Key Points

Aerodynamic losses vary, resulting in significant differences in thermal efficiency between the two blade designs.
Notably, the analysis reports losses of up to 15% in blades without film cooling.
Observational analysis across varying conditions evaluates the impact of film cooling on symmetric turbine blades.
Findings suggest that including film cooling could enhance overall efficiency in turbine blade designs.
