ABSTRACT:
A turbine blade for a turbine engine having one or more cavities in a trailing edge of the turbine blade for forming one or more vortices in inner aspects of the trailing edge. In at least one embodiment, the turbine blade may include one or more elongated cavities in the trailing edge of the blade formed by one or more ribs placed in a cooling chamber of the turbine blade. The elongated cavity in the trailing edge may have one or more orifices in the rib on the upstream side of the cavity. The orifice may be positioned relative to a vortex forming surface so that as a gas is passed through one or more orifices into the elongated cavity, one or more vortices are formed in the cavity. The gas may be expelled from the cavity and the blade through one or more orifices in an inner wall forming the pressure side of the turbine blade.
