Flow control grid

摘要

A flow control grid includes a plurality of channel assemblies connected to one another. Each of the plurality of channel assemblies defines a flow straightening section and a flow turning section. The flow turning section has an arcuate segment and a first substantially flat segment. The first substantially flat segment is positioned in the flow straightening section. The arcuate segment extends outwardly from the flow straightening section.

主权项

1. A flow control system for changing the direction of a fluid flow and developing a uniform flow velocity within a conduit, the flow control system comprising:
a flow distribution array comprising a plurality of tubes extending across a width of the conduit and secured between first and second sides of the conduit; a plurality of channel assemblies disposed adjacent to one another and arranged in a stepped configuration; each channel assembly for receiving a portion of the fluid flow including:
a flow straightening section including a plurality of flow plates positioned substantially parallel to one another and spaced apart from one another to define a plurality of flow paths between the spaced flow plates;a flow turning section disposed upstream of the flow straightening section, the flow turning section including a turning vane for directing a respective portion of the fluid flow substantially to the plurality of flow paths defined by the flow plates of the respective flow straightening section, the turning vane having an arcuate segment that extends outwardly and upstream from the flow straightening section: and the flow distribution array disposed upstream of the channel assemblies.
