ABSTRACT:
A straightening apparatus is constituted by a diffuser connected to an inflow pipe having a rectangular section to form an enlarged channel, and eight straightening vanes arranged inside the diffuser. The diffuser has a rectangular sectional surface, and is formed to increase its sectional area from a channel inlet to an outlet. Each straightening vane is arranged to set its surface along the flow direction. Instead of completely partitioning the channel by one straightening vane, the straightening vanes are respectively arranged on the upstream and downstream sides in the flow direction at intervals to form an opening portion at the middle portion of the channel without any partition.
