 March 31, 2003, 04:23 Question about Mixture Model #1 cao wei Guest   Posts: n/a According to Fluent6's manual, "The mixture model solves the continuity equation for the mixture, the momentum equation for the mixture, the energy equation for the mixture, and the volume fraction equation for the secondary phases, as well as algebraic expressions for the relative velocities (if the phases are moving at different velocities)." In other words, Fluent does not solve continuity equation, momentum and energy equation for each phase respectively. In my case, water is chosen as "primary phase", the "second phase" consists of 7 particle phases which are distinguished by their diameter. My question is: Now that Fluent does not solve continuity equation, momentum and energy equation for each phase respectively, and how does Fluent draw "stream function" and other parameters' profile for each phase, including water and particles? Best Regards Wei Cao

Mixture model treats flow as one phase flow with more components. Maybe itīs beter to use euler model in your case. It solves all equations for each individual phase.

 March 31, 2003, 09:22 Re: Question about Mixture Model #4 majestywzh Guest   Posts: n/a why don't you use the DPM to simulate the flow?you have noted that the secondary phase includes just only 7 diameter-different paticles.
