Hello,


I am using ANSYS Fluent 2020 r1 to simulate the filling stage of an injection mould. However, I don't know which material model is more suitable/correct for the flow of the molten polymer. In Fluent I can see the following options:


-Laminar
-K-Epsilon
-k-Omega
-Transition SST


From the turbulence models, the main ones are:


-RNG - Model
-Standard - Model
-Reynolds Stress Model
-Detached Eddy Simulation Model
-SST - DES Model
-Large Eddy Simulation Model





I wonder which one of these models could originate more realistic results. I appreciate any opinions regarding this matter. I thank you in advance.



Best regards,
Silva
