Solute transport during cyclic flow in fluid filled porous media was studied. The porous media was saturated with an incompressible fluid. The solute transport in the porous media is diffusion controlled in absence of fluid flow, which can be enhanced when the porous network is subjected to a cyclic flow with zero time average velocity. A mathematical model was used for analyzing the physical phenomenon and an effective macroscale diffusion coefficient for solute transport was obtained. The macroscale diffusion coefficient for solute transport was dependent on cyclic flow conditions and the geometry of the porous media.
