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.
