Sinclair Model + secondary turbulence
hi,
I met a problem when simulating two-phase flows using Sinclair model + secondary turbulence model in FLUENT4.5.6. 1> Turn on (Sinclair model + secondary turbulence). However, the equations to solve do not include particle-phase k & epsilon automatically. In this case, the simulation gives very good results! 2> Turn on (Sinclair model + secondary turbulence). Also, include particle-phase k & epsilon in the equations to solve. This time, the (time-dependent) simulation diverges! 3> only turn on Sinclair model (without secondary turbulence) The simulation results are not good. Can anybody tell me what is the difference between case-1 and case-2? I tried to seek more details in FLUENT manual, but can't find the answer. I want to clarify the governing equations and auxillary relations employed in the simulation. Thanks a lot in advance. |
