Definition of void fraction

Submitted by jagan1mohan on Thu, 12/17/2020 - 15:47

Hello All, the output file from a CFDEM simulation says that

"Reading voidfraction field voidfraction = (Vgas/Vparticle)".

Is it not that void fraction is Vgas/Vcomputationalcell?

Thank you,
Jagan Mohan.

In cfdemSolverPisoScalar/packedBedTemp/CFD/0/voidfraction file, I noticed 1 is assigned to voidfraction . But should it be smaller than 1 since particles inside?

Regards,
Brian
