I am currently testing the mixing abilities of different 2D geometries using two inlets (each filled with water) and one outlet.  I have not been able to find a way to differentiate the fluid of one inlet with the other in Fluent.  Is there a way I can differentiate one fluid from the other without having to use two absolutely different fluids?

Use species transport model with two same water components. Other way you inject some massless particles with some tracer ID to check mixing.

I have attempted to use the species transport model, but all of the contours/streamlines do not show the mixing from the two inlets.  Is there a way to give the fluid color for each inlet without changing the temperature?  Is there something wrong with my model settings or am I supposed to be looking at a specific animation/contour to show the mixing capabilities?  Also, given the geometry of the model, would an injection tracking system be more accurate?  Any help would be much appreciated.  

Thanks,

Hi Amine,

When I look into both inlets, I can only find a mass fraction for one of the fluids, as shown below.  I want to have different fluids coming in from different inlets.  How am I supposed to accomplish that given I can only change one fluid mass fraction?
