CFD Online Discussion Forums - Scalar Concentration

Hello to all,
As mentioned in the title i have to solve the concentration equation. My case is composed by a t-channel with two inlet.
Question: is there a solver for this particular case in OpenFOAM or i have to create my own solver based on scalarTransportFoam?
If i have to create my solver, can someone help me by traducing the equation to add because i don't know the syntax?

The equation is

Code:

dc/dt + v * grad(c) + laplacian(c)/(Re*Sc)

where Schimdt number is defined as Sc = nu/D where D is the diffusivity.

Thanks for your help and time.
