Laminar Static Mixer

In static mixers, also called motionless or in-line mixers, the fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing since it gives small pressure losses in this flow regime.

In this example, the flow in a twisted blade static mixer is studied. The mixing performance is evaluated by calculating the standard deviation of the concentration of the dissolved species that is being contained in one of the mixing streams.

The slice at the bottom shows the lighter and darker halves of the fluid with and without the dissolved species, respectively. As the fluid flows upward through the system, the two solutions are mixed and an almost constant concentration is obtained at the outlet.
