Abstract: The convection–dispersion equation (CDE) is the most widely used model for simulating the transport of dissolved substances in porous media. The dispersion term in the CDE lumps molecular diffusion and hydromechanical dispersion into an effective… read more here.

Abstract: Abstract We consider a class of a convection-dispersion equation describing the transport model of oil spilled in sea water with concentration-dependent dispersion and spatial velocity. A potential variable is introduced to the governing equation such… read more here.
