 March 13, 2012, 12:49 How to model Eulerian multiphase and Species Conservation at the same time? #1 New Member   Can Huang Join Date: Oct 2010 Posts: 8 Rep Power: 8 Sponsored Links Hallo ,everyone I am going to model a solidification process. I use the Multiphase segregated flow model to model the solidified phase and melt phase. These phases are all of multi-components. Problem is : When the Multiphase segregated flow model is selected, the Multi-Component Liquid models can not be selected. That's to say, in starccm+, How can I solve the species conservation equations while the mass conversation equations with volume fractions are solved? Thank you very much if any one have those experience

Its two components are iron and carbon. Carbon can diffuse and convect in the melt. I use Multiphase segregated flow to model the phase change(from liquid to solid), in each phase, at the same time I want to know the carbon distribution in the melt, so I have to solve the species conservation equations for each Euler phase(melt and solid). In the Material selection, Multi-Component Gas and Multi-Component Liquid models can solve the species equation, but in a single phase. Beside them, Multiphase Mixture can be choosen. So I choose Multiphase Mixture. Then under the Multiphase Flow Model there are two models, one is Multiphase Segregated flow, another is Volume of fluid (VOF). This is the problem! I want to solve the species equations with Multiphase segregated flow model. But if I use Multi-Component Liquid model I can't not choose Multiphase Mixture at the same time.
