Ensemble-averaged equations for reactive transport in porous media under unsteady flow conditions



Ensemble-averaged equations for reactive transport in porous media under unsteady flow conditions



Water Resources Research 35(7): 2053-2068



A method was presented for deriving the ensemble-averaged reactive solute transport equation for unsteady, non-divergence-free flow field conditions. The approach uses a cumulant expansion, Lie group theory, and time-ordered exponentials to develop the ensemble-averaged transport equation. The cumulant expansion is in powers of a alpha tau c, where alpha measures the magnitude of the perturbations of the transport and reaction operators and tau c is the correlation time of these perturbations.
