Problem with Multiphase and Reaction model interactions

    • nmontalbetti

      Hello, I'm having trouble defining a volumetric reaction function while using the multiphase model.

      Accoding to Fluent's User's Guide, the proper way of defining a reaction while using the VOF multiphase model is to do it through "Phase Interactions". However, when I "Phase Interactions" tab and select "Reactions", I can define the reactants and products, but I can't choose a Reaction Rate Function, the only option is "none".

      The only models turned on in this simulation are the multiphase model and the species model. I'm modelling a microreactor and I've already ran simulations with just the VOF model activated with no problems.

      This problem has occured both in Fluent 18.2 and 20.2.

      Hello, nOne probable reason for this is that a single energy equation is being solved [for both phases] for VOF and Mixture models. Whereas the full Eulerian-Eulerian model solves for separate energy equations for each phase. So for VOF and Mixture models, only a single temperature is available in each cell.nRegards,nSurya
