Asymptotic dispersion in 2D heterogeneous porous media determined by parallel numerical simulations
2007
Water Resources Research
9 We determine the asymptotic dispersion coefficients in 2D exponentially-correlated 10 lognormally-distributed permeability fields by using parallel computing. Fluid flow is 11 computed by solving the flow equation discretized on a regular grid and transport triggered by 12 advection and diffusion is simulated by a particle tracker. To obtain a well-defined asymptotic 13 regime under ergodic conditions (initial plume size much larger than the correlation length of 14 the permeability field),
