Document Type and Number:
WIPO Patent Application WO/2015/152381
Kind Code:
A1
Abstract:
Vane arrays define a flow path (R) through which a working fluid (G) flows and are formed in an annular shape by including a plurality of vane dividers (10) in a circumferential direction, each vane divider including a vane body (11). The vane divider (10) includes: an end wall portion (12, 13) which faces the flow path (R) and extends in the circumferential direction; and the vane body (11) which extends from the end wall portion (12, 13) and is located in the flow path (R). A circumferential end surface (15A, 15B) of the end wall portion (12, 13) has an inclined portion (16) that is inclined toward the flow path (R) and toward downstream of the turning direction of the working fluid (G) that flows through the flow path (R).
