A Query on Dense Discrete Phase Model - Transition Factor

Hello,
I am a bit new to Ansys FLuent, especially when it comes to modeling of multiphase flows. I have a query on Dense Discrete Phase Modeling. In the discrete phase dialogue box there is a parameter labelled "Volume Fraction Approaching Continuous Flow Limit" that can be checked or unchecked. Now my questions are as follows. 1) What is the significance of this parameter? In the Ansys Fluent theory guide it is stated that if the "Transition Factor" is 0.75, then the transition volume fraction is 0.75*(3/4) = 0.5625. Now what does transition volume fraction signify? Does it mean that if this volume fraction is exceeded, the solver will start treating the discrete phase as continuous phase? 2) If "Volume Fraction Approaching Continuous Flow Limit" is unchecked, what happens? Thanks a lot and would really appreciate a prompt reply! |
