Hey guys!

I'm trying to simulate the motion of particles in a centrifuge using reactingParcelFoam. My fluid is Newtonian and there's turbulent dispersion involved as well as a rebound interaction between the particles and the wall of the centrifuge. Here's my code so far:

    version     2.0;
    format      ascii;
    class       dictionary;
    location    "constant";
    object      reactingCloud1Properties;

I've left some stuff out, but I'm wondering what I should use for the particleForces. Right now it's just sphereDrag and gravity, but should I include a centrifugal force contribution? Certainly there's a centrifugal force in there, but I don't know if it's already implicitly part of the solving method. If I do need to include centrifugal force, how do I do so?
