High turbulent viscosity & Discete Phase
Hi everyone, I am trying to simulate a fluid flow composed by a mixture of h2o, o2 and n2 at high temperature which needs to be cooled down by water injection, modeled through droplets exploiting DPM. Once I run the model the calculation proceeds, but at every iteration Fluent reports "turbulent viscosity limited to viscosity ratio of 1e+05", for the entire domain. From what I observed, this usually happens due to poor initialization (therefore only for first iterations) or completely wrong BC at inlets for turbulence, but I am quite sure this is not the case. I state that I am not so skilled in DPM, is there anyone who has already experienced this issue? Thanks!
