CFX multiphase flow with poly-dispersed approach?

Hi everybody I have started the boiling flow simulation (RPI model) in a rod bundle system. First I did it with the mono approach and I obtained convergence. After that, I have tried it with the...

What could be reason that as I increase the mesh, mesh dependency is increasing up to a point and after that point it is decreasing?

I am simulating (CFX) a pipe with a turbulence promoter in it. I am using RNG k-e turbulence model yplus is lower than 1. For mesh independency analysis I am using turbulence kinetic energy as a...
