Hello Team, I'm looking to compare twoPhaseEulerFoam (2PEF) and CFDEM setup via simulating minimum fluidization velocity. In CFDEM setup, inlet velocity at the inlet boundary in the simulation is exactly same as we give in U dictionary. That is, I defluidize from 0.6 m/s to 0.0 m/s in 10 secs and functionObject confirms this.


In CFDEM, I use type flowRateInletVelocity; for gas.
In 2PEF, we have type interstitialInletVelocity; and it depends on alpha.air;


Value applied at inlet boundary is very different from one specified in U dictionary.


1. How do we maintain exact gas velocity in 2PEF?



Thank you,
