Abstract:
1. A mixer for mixing a fluid having a property varying along a flow direction of the fluid, the mixer comprising: an inlet configured for receiving an inlet flow, an outlet configured for providing an outlet flow, and a plurality of flow channels coupled between the inlet and the outlet, a flow distributor for distributing the inlet flow into the plurality of flow channels so that each flow channel receives a partial flow from the inlet flow, and a flow combiner for combining the partial flows from the plurality of flow channels to the outlet flow, wherein each flow channel comprises a first flow section having a hydraulic resistance substantially representing a hydraulic resistance of the flow channel, one or more of the flow channels each comprise a second flow section coupled in series with the first flow section of the respective flow channel, each second flow section comprises a volume that is flown through by the fluid and delays fluid propagation from the first flow section to the flow combiner by a time required by the respective partial flow to pass the volume of the respective second flow section, and the distribution of the partial flows into the flow channels is substantially independent of the viscosity of the fluid.
