I want to make a simulation for two different color liquid mix together, lets say fluid A ( red in color) and fluid B (yellow in color). I want to simulate it in Fluent to determine the diffusion rate between this two fluids. Can I make it in Fluent to look the changes of the color when this two fluids mix together??

Thanks in advanced.

Color is a function of the human visual system, and is not an intrinsic property. The related physical property for the color of a solution is the transmission or absorption spectrum. And I'm not too sure if CFD techniques can provide solution to the calculations involving theory of spectra.
