Dispersion Modelling in Fluent

visser1975 · November 12, 2013, 15:40

Hi Guys,
I am trying to model the dispersion of a dye in water, when the flow is subjected to an oscillating periodic gradient. I am not familiar with non reactive species transport in Fluent and am looking for a tutorial(video or pdf) of the same. In case someone can guide me in this regard, I request your help.

Thanks Vignesh!

An opinion I heard is that species transfer model in Fluent is required only when the mixing of 2 flows changes the properties of the fluids. Is that true?

For instance Fluent has a heat exchanger model, but it is not necessary to use the heat exchanger model to simulate heat transfer. Is it the same with the species model?

I think species transport model is fine for this case.
