Hi friends
I wanna know in Eulerian multiphase model, how fluent calculates the buoyancy force of second phase!? is there any official document or equation to describe it? |

If still looking for the answer, the buoyancy force in multiphase model is calculated as the density difference between the phases. It is the operating density of the lightest phase in operating condition panel that takes care of this body force.

fluent solves only some equations! momentum, continuity, energy and...!
I want to know, how did fluent determine buoyancy force in eulerian model equation? is this only in momentum equations? or... |

It is only the momentum equation where the buoyancy force as a difference between two phases is included. Have a look at this FLUENT guide page:

there isn't enough description about fluent method to calculation buoyancy force!
I need equations that solved by fluent! Thanks |
