Numerical modelling of micromixing in a T-mixer flow at low Reynolds numbers

Highlights  CFD simulations are performed to study micromixing in a laminar microfluidic flow.  Segregation indices are calculated using the Villermaux-Dushman protocol.  Micromixing is modelled directly with CFD and indirectly with a lamellar model.  The two solutions are compared in terms of computational cost and analysis times.
