Hi everyone,
I am trying to simulate ammonia and water emission from ammonia water in a two dimentional model using Fluent 6.3.26. The ammonia water fills in a tank which is connected with a wind tunnel. The air is supplied for one side of the wind tunnel and exhausted from the other side. THe case is isothermal. I tried tutorial 17 and 19 and read part of 23 chapter in user's guide, but I am still not clear for the settings of the simulation. I suppose the following models and boundary conditions should be considered: (1) velocity inlet, air, water-gas and ammonia gas flows with the same velocity and volume fraction will be set; (2) pressure outlet; (3) low Reynolds k-e model; (4) Multiphase flow model, VOF or Mixture or Eulerian, I am not sure; (5) the ammonia water in the tank, I guess there is chemical reaction, such as: NH4--NH3+H, I don't know how I can define it here; (6) Should the evaporation model be included since there is water evaporate into the air? (7) Should I define something for the ammonia emission from the liquid-gas interface? (8) Should I define the interface in the model? Thank you very much. Kind Regards, Li |

Is it possible to model the ammonium chemical reaction in the ammonia water with multiphase model in FLuent 6.3.26?
