Looking for advice on what drag force constant to use for a multiphase flow (particle in water)

Also keep getting divergence instead of convergence, looking for any possible advice?

Can you elaborate a little? What do you mean by a drag force constant?

Divergence of a solution can occur for a wide range of reasons. A good place to start would be your temporal and spacial discretizations (i.e. your time step and your mesh size) of your simulation.

Sorry, I should have been more specific!

I'm running multiphase segregated flow, with two Eulerian phases - water, and a suspended particle. I'm wondering what drag force co-efficient to use for the phase interaction? Re = 800.
