Abstract
Diffusion in steady fluid flow through a porous medium with large fluctuations in the pore diameters is studied. For incompressible fluids, there are singular corrections to hydrodynamics in three dimensions and logarithmic divergences in . When the constraint of incompressibility is relaxed, we recover recent results for diffusion in a random environment.
