Abstract
A simple reinterpretation of the lattice Boltzmann equation is presented that allows it to track passive scalar dynamics in grossly irregular geometries without adding any new ingredient to the basic hydrodynamic algorithm. The scheme is numerically demonstrated for two representative test cases: diffusion in two-dimensional fractal media and Taylor hydrodynamic dispersion.
