Hi,

Can OpenFOAM simulate the injection of two different incompressible fluids with the same physical properties (when it comes to fluid dynamics), including turbulent flow. Can it output the result in a way which allows me to visualize the fraction of the fluids at every point?

I've been testing OpenFOAM the last two days, but I didn't find a clear answer (neither here nor via Google).

I looked at the sloshingTank3D (interDyMFoam) and the elbow (icoFoam), as well as some others. What I couldn't answer for myself:

* Can I add injection of a specific fluid instead of setting a general velocity field?
* Can I "tag" a fluid, so I can identify it in ParaView?
* Does both work with turbulent flow?

(I currently evaluate different options for simulating contrast fluid in blood vessels)
