Jos stam implementation with OpenFOAM

I am trying to implement Jos stam's real time fluid dynamic for games using OpenFOAM. (http://www.dgp.toronto.edu/people/st.../pdf/GDC03.pdf). why i choose this paper because, I need to demonstrate advection, projection, diffusion of fluid(Navier stoke equation).
which solver do I need to use to solve navier-stoke equation(advection, projection, diffusion) in Openfoam?. Give me suggestion to simulate smoke flow as per Navier stoke equation (density solver, velocity solver).

I found Jos Stam's paper very interesting. But you must be aware that what this author does is very different from what OpenFOAM does. He is trying to do a fast simulation that looks like a real fluid flow. He doesn’t care if he is solving exactly the Navier-Stokes equation. He is mainly preoccupied to have a simple algorithm. On the other hand, OpenFOAM, if correctly used, will solve the Navier-Stokes equation with the desired degree of accuracy, giving precise results for engineering applications.
I have no experience with smoke flow in OpenFOAM but looking at the user guide (page 88), it seems that a solver for particle tracking flows would do the job.
I suggest that you think carefully if its worthwhile to use OpenFOAM for this application. Implementing a solver like the one of the paper seems to be much easier than adapting an OpenFOAM solver for a specific problem.
