Document Type and Number:
Japanese Patent JP2021148125
Kind Code:
A
Abstract:
To provide an exhaust diffuser hub structure capable of reducing pressure loss inside of an exhaust diffuser by reducing pressure loss generated from an end portion of a hub positioned at a center in a longitudinal direction of the exhaust diffuser and flow separation phenomenon.SOLUTION: A hub disposed along a center in a longitudinal direction of an exhaust diffuser, has a hub extension portion having a transverse cross-sectional area smaller than a transverse cross-sectional area of the hub, while extending from a downstream end portion of the hub along the longitudinal direction, and the hub extension portion is concentric to the hub so as to form a step with respect to the hub along the circumference of the hub extension portion.SELECTED DRAWING: Figure 4
