Abstract
An object is to provide a mixed flow turbine, wherein intermediate blades having an intermediate height are provided between main blades of the mixed flow turbine, thus improving an impulse blade turbine characteristic and reducing the moment of inertia for a rotor blade as a whole, thereby improving the efficiency and transient response. The mixed flow turbine includes: a turbine rotor blade; a turbine housing; a scroll partition walldividing a scroll chamber; a shroud-side inflow passagewayformed on the side of a shroud-side partition wall surface; and a hub-side inflow passagewayformed on the side of a hub-side partition wall surface, wherein the rotor bladeincludes: main bladesformed with a height spanning the entire extent between a hub outer circumferential surfaceand the inner periphery surface of a shroud portion; and intermediate bladesarranged in the circumferential direction between the main bladesand arranged so as to extend from the inlet portion of the main bladesto an intermediate portion and having an intermediate height with respect to the height of the main blades, wherein a fluid from the hub-side inflow passagewayflows in through front edges of the intermediate blades
