Abstract
A turbine blade includes an airfoil having opposing first and second sides and an internal passage extending longitudinally therebetween. A plurality of first turbulator ribs extend from the first side into the passage, and a plurality of second turbulator ribs extend from the second side into the passage. The first and second ribs are different in configuration from each other for obtaining different heat transfer enhancements on the first and second sides for reducing pressure losses and cooling air flow requirements.
Claims12
A turbine blade having a longitudinal axis comprising:
- an airfoil having a first side and an opposite second side joined together at a leading edge and a trailing edge and extending longitudinally from a root to a tip, and an internal passage extending longitudinally between said first and second sides for channeling air to cool said airfoil;
- a plurality of parallel first turbulator ribs extending from said first side into said passage and having substantially identical configurations including a first height, a first width, and being longitudinally spaced apart at a first longitudinal spacing for providing a first heat transfer enhancement for said first side;
- a plurality of parallel second turbulator ribs extending from said second side into said passage toward said first ribs and having substantially identical configurations including a second height, a second width, and being longitudinally spaced apart at a second longitudinal spacing for providing a second heat transfer enhancement for said second side;
- and
- said first and second ribs being different in configuration from each other so that said first and second enhancements are different.
