Abstract
A component for a hydraulic turbine includes a pressure side and a suction side that each extend between a leading edge and a trailing edge of the component. At least a part of the trailing edge includes a plurality of patterns along at least a portion of the trailing edge, the plurality of patterns configured to reduce an amplitude of Karman vortices and disorganize a flow downstream of the trailing edge.

A component for a hydraulic turbine, the component comprising:
- a pressure side;
- a suction side;
- the pressure side and the suction side extending between a leading edge and a trailing edge of the component;
- and
- at least a part of the trailing edge comprising a plurality of patterns along at least a portion of the trailing edge configured to reduce an amplitude of Karman vortices and disorganize a flow downstream of the trailing edge.
A method for improving dynamic and vibratory behavior of a component of a hydraulic turbine that includes a pressure side and a suction side extending between a leading edge and a trailing edge of the component, the method comprising forming a plurality of patterns along at least a portion of the trailing edge configured to reduce an amplitude of Karman vortices and disorganize a flow downstream of the trailing edge.
