Abstract
A fluid machine includes a rotatable hub; a plurality of blades spaced apart from one another along a circumferential direction with respect to a rotation center of the hub; and a shroud extending along a circumferential direction with respect to the rotation center of the hub and covering the plurality of blades. The shroud includes: a flow passage, the flow passage formed to be recessed with respect to an inner surface of the shroud facing the blades; and a plurality of resonators provided in the flow passage.
Claims11
A fluid machine comprising:
- a rotatable hub;
- a plurality of blades spaced apart from one another along a circumferential direction with respect to a rotation center of the hub;
- and
- a shroud extending along the circumferential direction with respect to the rotation center of the hub and covering the plurality of blades, the shroud comprising:
- a flow passage, the flow passage formed to be recessed with respect to an inner surface of the shroud facing the blades;
- and
- a plurality of resonators provided in the flow passage,
- wherein the shroud comprises:
- an inlet portion configured to guide an inflow of fluid toward the plurality of blades;
- and
- an outlet portion configured to guide discharge of the fluid that has passed through the plurality of blades,
- wherein the plurality of resonators are arranged in the flow passage with a uniform density in an entire area of the flow passage from the inlet portion of the shroud to the outlet portion.
