Mixing regimes and the scale up problem for multiphase flow in porous media
Frederico Furtado, Felipe Pereira · 1970
We examine fluid mixing dynamics for two-phase, immiscible flow in heterogeneous porous media. To assess the combined effect of nonlinear flow instability and heterogeneity, we solve the model problem numerically, using large suites of realizations of stochastically generated permeability fields. Different mixing regimes are identified, depending on the relative importance of nonlinearity in the flow equations and heterogeneity.
