ABSTRACT:
A blade row for a rotary machine includes a radially inner endwall, a radially outer endwall having a radially inner surface, and an airfoil including a root section coupled to the inner endwall and a tip section coupled to the outer endwall such that the airfoil extends radially between the inner and outer endwalls. The radially outer endwall includes a projection extending radially inward from the outer endwall inner surface such that the outer endwall inner surface includes a non-axisymmetric shape.
