3d liquid diffusion using species transport

    • jonny

      Hi, i am trying to analyse diffusion of a colored glycerol-water mixture droplet into an uncolored one, both with the same fluid properties, inside a domain filled with air.

      I am currently trying to apply the species transport model to apply diffusion parameters.
      My question is how to apply this to the droplets where one has a concentration of 1 and the other 0, to measure ones diffusion into another after coalescence.
      Secondly would i require to use a multiphase model?

      You might need to use “Multiphase” model, if you have liquid and gaseous phase fluids in your domain with Species Transport model. Therefore, yes. You need to use both the models.
