Resumen de: AU2023347620A1
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.

The present application discloses a blade and an axial-flow impeller using the same. The present application provides a blade, comprising a blade tip, a blade root, a leading edge and a trailing edge, wherein the leading edge and the trailing edge extend from the blade tip to the blade root, respectively. The blade is capable of rotating about a rotation axis X which is perpendicular to a normal plane. In a projection of the blade on the normal plane, a circumferential included angle between the leading edge and the trailing edge forms a wrap angle, and the wrap angle decreases gradually from the blade root to a middle blade height of the blade and increases gradually from the middle blade height to the blade tip. Wherein, the middle blade height is an arc line formed by center points of the blade tip and the blade root along a radial direction. The blade of the present application allows for significantly reduced turbulent vortices and reduced intensity in the vicinity of the junction of the leading edge and the blade tip of the blade and in the vicinity of the junction of the trailing edge and the blade tip of the blade during the operation of the axial-flow impeller, leading to evenly lightened load of airflow on the blade, more uniform distributions of velocity and pressure, reduced velocity and pressure pulsations, and reduced noise.
