Cooling system including mini channels within a turbine blade of a turbine engine |
摘要 |
A turbine blade for a turbine engine having a cooling system formed from one or more cooling channels having a plurality of mini channels. The cooling system may include first ribs forming a first passageway of mini channels in which the cross-sectional area of the cooling channel is reduced, thereby increasing the velocity of the cooling fluids and the internal heat transfer coefficient. The cooling system may also include second ribs forming a second passageway downstream from the first passageway a distance sufficient to prevent the formation of a fully developed boundary layer and allow the cooling fluids to fully expand after exiting the first passageway. The cooling channel may also include a plurality of protrusions extending from surfaces forming the cooling channel to create turbulence and prevent formation of a fully developed boundary layer.
