Overview

This design uses additive manufacturing to optimize cooling in a hydrogen fueled gas turbine, demonstrating improved thermal management.

Key Points

  • The design effectively maintained wall temperatures below the melting point of Inconel 718, ensuring reliability under extreme conditions.
  • Computational simulations showed coolant flow efficiency within the developed airfoil, validating the cooling strategies employed.
  • Manufacturing utilized advanced techniques to create a complex geometry, enhancing the cooling performance and efficiency of the nozzle.
  • Experimental testing in a wind tunnel facility confirmed predictions about the nozzle's thermal performance and design efficacy.
