SWIRLING FLOW ADJUSTING DEVICE

Title:

SWIRLING FLOW ADJUSTING DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/215990

Kind Code:

A1

Abstract:

This swirling flow adjusting device (100) is provided with: a first space forming part (10) that forms a first space (11); a second space forming part (30) that forms a second space (31); and a third space forming part (50) that forms` a third space (51). The first space has a first inlet (17) and a first outlet (18). The second space has a second inlet (33) connected to the first outlet, and a second outlet (34). The third space has a third inlet (57) connected to the second outlet, and a third outlet (58). In a case in which a vector, obtained when a vector from the first inlet to the first outlet is projected onto a plane perpendicular to a direction in which a fluid is discharged from the third outlet, is a first projection vector, and a vector, obtained when a vector from the third inlet to the third outlet is projected onto the plane, is a second projection vector, the direction of the first projection vector and the direction of the second projection vector are different. Accordingly, a swirling flow in a flow passage is adjusted with a compact configuration without specifically installing a member in the flow passage.
