Abstract
When A is a flow-path cross-sectional area of the scroll part, and R is a distance from a centroid of a flow-path cross-section of the scroll part to a rotational axis of the turbine rotor blade, the scroll part is configured so that a first graph, having a horizontal axis representing an angular position θ in a circumferential direction of the scroll part and a vertical axis representing ratio A/R of the flow-path cross-sectional area A to the distance R, at least partially has a concave distribution. The scroll part includes a first section belonging to a first angular range in the circumferential direction, and a second section belonging to a second angular range downstream of the first angular range in the circumferential direction and having a smaller throat width than a throat width of the first section in an axial direction of the turbine rotor blade.
