Incompressible, miscible mixing of two fluid stream OpenFOAM

I am very new to openFOAM and this forum. To get feel of OpenFOAM i decided to setup a test case involving mixing of two fluid stream (compressible and miscible).
It is not a two-phase situation i am dealing with, it is one phase (water) at two different temperatures mixing in a T-junction.
Can anyone suggest me which solver to use?

I'm no expert on this subject, so until someone more experienced responds, here's what I know...
If you check the folder "heatTransfer" in the OpenFOAM "tutorials" folder, you'll find these solver tutorials:

Did you find out which solver to use and what boundary conditions to use?
I am also looking at the same problem and have been stuck on it for three days now. I am not able to find this simple example anywhere.

multiphase flow solver would be the option in my guess

since the pure substance is having different thermodynamic states before mixing, it may be somehow relevant to treat them as two different fluids? if the compressibility can be ignored, twoLiquidMixingFoam is there as a standard solver in OpenFoam. otherwise, you need to modify this solver by adding the codes related to the compressibility of the fluids. still you can search for other relevant solvers which may best fit your physical model.
