How to Simulate Particle Tracing in a Laminar Static Mixer
Laminar static mixers are used for the accurate mixing of fluids (both liquid and gas). Unlike a mixer containing moving blades, a static mixer contains twisted stationary blades that are positioned at different angles throughout the cylindrical flow channel of the mixer. When a fluid is pumped through the channel, the alternating directions of the cross-sectional blades cause the fluid to become mixed as it passes along the length of the channel. This mixing technique allows for precise control over the amount of mixing that takes place throughout the process — even in the mixing of very small amounts of fluid. In a recent video, we demonstrated how you can use COMSOL Multiphysics along with the CFD Module and Particle Tracing Module to evaluate the performance of a laminar static mixer.
