Static In-line Mixers

Simulation of a static inline mixer that was done in the MEC E 539 course under supervision of Dr. Hemmati. Other contributors were Mattias Emond, Santhosh Virappane, Fulin Song and Lap Au-Yeung.

Static mixers are a specific type of mixer in which no power is needed. The fluid is churned by blades attached either to the pipe wall or a rod running along the pipe centerline with the fluid pumped through. Turbulence flow regime is characterized by randomness, dissipative, and diffusive nature. In this study, turbulent kinetic energy (TKE) was taken as a representation of mixing. Three cases were analysed with 5, 7, and 9 mixing planes. A trade-off was observed between TKE and pressure drop across the mixer structure along with drag coefficient.?

Below, the geometry, final grid, TKE on two different flowrates, and streamlines for bith laminar and turbulent cases are provided.
