Weave Design Enhances Heat Transfer and Reduces Thermal Stresses in Gas Turbines
Summary
A Purdue University graduate student has developed an improved cooling paradigm for the trailing edge of turbine airfoils. This weave design combines several geometrical concepts to efficiently utilize the internal flow to cool the trailing edge material effectively and uniformly. When compared to three advanced cooling strategies, the weave design provided more efficient and uniform cooling and caused less unnecessary pressure loss.
