Simulating Particle Motion in a Co-flow of Miscible Fluids

Please login with a confirmed email address before reporting spam

Hi all,

I am attempting to create a model of a microfluidic device that consists of a co-flow of two miscible fluids (one viscoelastic fluid and another sample fluid containing spherical particles approx 5um in diameter). The goal is to obtain velocity profiles of the co-flow, as well as a time-based model to simulate and track the motion of particles within the co-flow.

The problem is that the "Multiphase Flow" -> "Two-Phase Flow" modules in COMSOL Multiphysics are used to model two immiscible fluids where as my model requires the co-flow of two miscible fluids.

Could anyone please advise as to which modules would be best to create such a model?

Kind Regards, Dan
