trystwithgaurav is on a distinguished road

I am trying to model the flow of calcium carbonate particles in water through a pipe with diameter 0.1016m with the velocity of particles as 0.5m/s and that of water as 0.78m/sec. I am using the mixture model. I am running the simulations with the convergence criteria of residuals at 1e-5 but the continuity and the Z-velocity doesnt seems to be converging at all even after something around 11100 iterations. They still fluctuate at around 1e-2.

Can anybody guide me for how to achieve my solution to converge? If under relaxation factors are the deciding ones, what should be the values i should actually use?
