Why don't you use the time-averaged value of nuSgs/nut? I don't think this will make a very big difference compared to what you want to do. I still don't get why you want to do it this complex...

For the right hand side, don't you get something like fvm::grad(nuEff) & fvc::grad(U) + nuEff * fvc::laplacian(U) or something like that, which you can solve if you supply boundary conditions?...

If you work out the brackets in the term on the right hand side, can't you just solve it like any other equation in OpenFOAM? So you use fvc instead of fvm on the terms with p and U and solve for...
