Claims

[Scope of utility model registration request]

This is a flow straightening device that aims to equalize the flow velocity distribution in a cross section immediately after an annular diff user, in which a plurality of straightening hollow struts are provided radially in the radial direction on the exit side of the diffuser, and the hollow struts are arranged in a range where the flow velocity is large in the flow velocity distribution in the annular portion. A flow rectifier for an annular diffuser, which has an intake opening on the front surface, and further has notches at the joints of an inner cylindrical ring with each hollow strut, in which each hollow strut is erected on an outer peripheral surface.
