 May 5, 2010, 02:24 Equations solved for multiphase #1 Senior Member   Join Date: Mar 2009 Location: Indiana, US Posts: 185 Rep Power: 9 Hi, I'm solving a multiphase simulation, Liquid - Continuous Gas - Dispersed Particle model, with turbulence. I had a basic question with regard to the equation solved (as mentioned in the Solver). It solves momentum ,continuity and turbulence (mass) for both phases individually. And there is an additional "p-vol" equation being solved, does this somehow relate to the volume fraction? Cos when i plot the p-vol variable at outlets (while solving), it plots the mass flow. Any help appreciated. Thanks Luke

At the boundarys, apart from the phase momentum, p-vol and phase turb variables, i see 2 phase mass variables. Are they no derived from the phase continuity? Question might sound dumb, sorry, but i'm just thinking out loud. Thanks Luke
