Laminar Static Mixer

In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure losses in this flow regime. This example studies the flow in a twisted-blade static mixer. It evaluates the mixing performance by calculating the concentration’s standard deviation.

This model studies the mixing of one species dissolved in water at room temperature. The geometry consists of a tube with three twisted blades of alternating rotations. The Laminar Flow and Transport of Diluted Species interfaces are used with a Stationary study type.

MIXERS: As a fluid flows upward through the static mixer, the two solutions are mixed and an almost constant concentration is obtained at the outlet.
