Title:
RADIAL TURBINE
Document Type and Number:
WIPO Patent Application WO/2012/102145
Kind Code:
A1
Abstract:
Provided is a radial turbine with a reduced number of parts and reduced cost which is capable of handling fluids having multiple pressures with a single or an integrated turbine wheel. This radial turbine (100) is equipped with a radial turbine wheel (15), which is equipped with a main passage (26) the blade height of which increases gradually as the main passage curves from the radial direction to the axial direction, and the radial turbine wheel converts revolving energy, from a fluid which flows into the main passage (26) from an outer circumferential-side main inlet (21) and the main component of which is a radial flow, into rotative power. A secondary inlet (29), through which flows a fluid having a pressure (P2) that differs from the pressure (P1) of the fluid supplied from the main inlet (21), is formed on the shroud side of the radial turbine wheel (15) at a position separated from the main inlet (21) in the radial direction and the axial direction. As for the shape of the blade forming the secondary inlet (29), the center line of the blade (19) at the surface perpendicular to the axis of radial turbine wheel (15) slants toward the direction of rotation at a prescribed angle with respect to the radial direction.
