A fluid flow turbine blade assembly for a turbine rotor includes a blade and a deflector extending spanwise along at least a portion of the blade. At least a portion of an upstream surface of the deflector, along at least a portion of a span of the deflector, has a concave shape in a chordwise direction such that at least a portion of a chord line between leading and trailing edges of the deflector is disposed outside a profile defined between the upstream surface and a downstream surface of the deflector. The deflector has a substantially uniform thickness or a chord-wise varying thickness between the upstream surface and the downstream surface. The deflector alters fluid flow over the blade so as to increase the blade's contribution to global torque generated by the assembly so that, with the deflector's torque contribution, the global torque of the assembly is greater than the global torque that would be generated by the blade alone without the benefit of the deflector.
