US Patent 12085094 Pressure exchanger with flow divider in rotor duct

A pressure exchanger includes a rotor including rotor ducts that extend parallel to each other. The pressure exchanger further includes a flow divider that has a substantially flat shape and is located in the rotor ducts, where the flow divider partitions an inner space of one of the rotor ducts into flow paths configured to communicate fluid. The flow divider defines an aspect ratio of each of the plurality of flow paths, where the aspect ratio is a ratio of a width of one of the flow paths in a radial direction with respect to an axial length of one of the flow paths in the axial direction.
