ANSYS FLUENT – Static Mixer


Static mixers can be applied to a wide range of process operations, including dosing, dispersion, laminar flow heat exchange and emulsion formation. They offer many key benefits for combining liquids, gases and powders and they are tried, tested and trusted in many different industries. Mixing action is achieved by the continuous splitting, extension and transportation of the components. Motionless mixers use a series of precisely configured mixing elements to process the components. Differences in concentration, temperature and velocity are equalized over the flow cross-section.

This is a basic tutorial about static mixer using ANSYS FLUENT. In this tutorial, you will learn how to create the geometry and the mesh, you will learn how to modify the setup too and visualize the results (internal planes and streamlines).


  • Static mixers deliver a high level of mixing efficiency, therefore the consumption of dosed chemicals and formation of byproducts can be dramatically reduced.
  • They eliminate the need for tanks, agitators, moving parts and direct motive power and they allows to gain highly efficient mixing with low energy consumption.
  • The energy required for mixing is efficiently extracted as pressure drop from the fluid flow through the elements. Mixers are invariably installed in existing systems without reducing the capacity of existing pumps.
  • The installation is very easy, no special skills are required other than normal engineering skills.
  • Mixers have no moving parts and are virtually maintenance free.
  • Static Mixers are available in all standard pipe sizes and, in the case of open channel designs, are available in any size with no upper limit.
  • Each Static Mixer is carefully designed to meet the specific requirements of each application.
