Hello,
the energy equation in reactingTwoPhaseEulerFoam and other solvers in OpenFOAM 3.0.0 looks a litte bit different from the other versions.
Here the code for the EEqn in the reactingTwoPhaseEulerFoam:

if (E1Eqn.valid())
{
E1Eqn =
(
E1Eqn
==
*heatTransfer[phase1.name()]
+ alpha1*rho1*(U1&g)
+ fvOptions(alpha1, rho1, phase1.thermo().he())
);

E1Eqn->relax();
fvOptions.constrain(E1Eqn());
E1Eqn->solve();
}

The most is clear to me but what is the meaning of: U1&g

Do anybody know what the meaning of this expression is and where it is calculated?
