Turbine airfoil with near-wall spiral flow cooling circuit |
摘要 |
A turbine blade with a plurality of spiral flow cooling channels spaced along the walls of the blade. Each spiral flow cooling circuit includes two adjacent channels that twist about each other in a radial direction of the blade to form a spiral flow path. The two spiral flow channels meet at intersections such that the flows mix and produce turbulence in the flows. Two adjacent spiral flow channels intersect at a plurality of intersections spaced along the radial direction of the blade. The channels include trip strips arranged in a spiral shape within the channels to promote turbulent flow. A plurality of the spiral flow channels are arranged along the pressure side and suction side of the blade to provide near wall cooling.
