Abstract
PURPOSE: To improve the performance of a diffuser by forming a plurality of vortex generating grooves which generates vortex in the reverse direction to the direction of revolution of a vane wheel, along the inlet circumference of a vaneless diffuser, and forming uniform the stream at the diffuser inlet part.
CONSTITUTION: A plurality of vortex generating grooves 11 and 12 are formed along the surface of the flow ppassage on the inlet circumference of diffuser plates 8 and 9. Into said vortex generating grooves 11 and 12, the swirling flow which flows-out from the exit ends of the core plate 3 and the side plate 2 of a vane wheel is lead, and small vortex stream in the reverse direction to the direction of revolution of the vane wheel is formed. As a result of this, a plurality of small vortex are formed at the inlet part of the diffuser, and the stream in the vicinity of the surface of the diffuser flow passage is shifted from the direction (a) to the direction (b), and uniform distribution in the direction of the width of the flow passage can be obtained, and exfoliation of the boundary layer on the wall surface is prevented.
