I want to get the projectile of microspheresc in microfluidic chip.

I am trying to get a complete solution to Navier and Stokes equations at low (unity) Reynold number. (viscous and inertial ).

is there any model that I can use to simulate the fluid behavior ??
anyone has an idea about how should I go with the microspheresc path tracing?

Thank you in advance

I am facing same problem.
I asked this problem to Comsol company, then it just said 'you use the force term in particle tracking module'
But now I still don't know how to add the inertial lift force.
If you solve the problem, remaining the comment. Thanks.

I think the drag force in particle tracing module can be used as inertial lift force.
Best wishes,
