Abstract

A turbine includes: a turbine scroll flow path; a turbine blade wheel disposed on a radially inner side with respect to the turbine scroll flow path; and a blade included in the turbine blade wheel, the blade having a leading edge inclined to a side opposite to a rotation direction side of the turbine blade wheel as the leading edge extends from a hub side to a shroud side, the leading edge having an inclination angle greater than 0° and less than or equal to 45° with respect to an axial direction of the turbine blade wheel as viewed in the radial direction.

Claims (6)

1. A turbine comprising:

a turbine scroll flow path;

a turbine blade wheel disposed on a radially inner side with respect to the turbine scroll flow path; and

a blade comprised in the turbine blade wheel, the blade including a leading edge inclined to a side opposite to a rotation direction side of the turbine blade wheel as the leading edge extends from a hub side to a shroud side, the leading edge having an inclination angle with respect to an axial direction of the turbine blade wheel as viewed in a radial direction within a range of 10° to 30°, the leading edge has a linear shape, and the blade includes a trailing edge having a linear shape,

wherein the inclination angle is constant from the hub side to the shroud side.

2. A turbocharger comprising the turbine according to claim 1 .
