whats the mathematical equivalence of this formula?
which equation is used in rhoCentralFoam?
// --- Solve momentum
        solve(fvm::ddt(rhoU) + fvc::div(phiUp));

        U.dimensionedInternalField() =
        rhoU.boundaryField() = rho.boundaryField()*U.boundaryField();

        volScalarField rhoBydt(rho/runTime.deltaT());

        if (!inviscid)
                fvm::ddt(rho, U) - fvc::ddt(rho, U)
              - fvm::laplacian(muEff, U)
              - fvc::div(tauMC)
            rhoU = rho*U;

Hi Ehsan,

I don't know the answer, but I've picked on the following breadcrumbs on this topic:
Check the PDF files on the last link.
