I want simulate a two stage centrifugal pump, by Fluent. Pump contains: inlet that is a bent pipe, two impellers, diffusers and outlet is a dual volute. I want use Multiple Reference frame (MRF), but, whereas the pump geometry are 3-D and complex shape, I have many problem for simulate in FLUENT. I need help.
Problems are in the below:1-What value suitable for “Turbulent Intensity” for pump inlet? 2% or more percent?
2-What is correct turbulence model? Standard k-e? Or RNG k-e? Or Realizable k-e?
3-What value suitable for “Under relaxations” for convergence a solution?
4-What suitable method for ” Discretization pressure” (with consideration to model)? Standard? Or PRESTO! ? or etc?
