jon.fourn is on a distinguished road
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?

Thanks
