Second law aerodynamic losses from symmetric turbine blades with and without film cooling

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.
