Abstract:
Two-dimensional advection-diffusion equation with variable coefficients is solved by the explicit finite-difference method for the transport of solutes through a homogeneous, finite, porous, two-dimensional, domain. Retardation by adsorption, periodic seepage velocity, and a dispersion coefficient proportional to this velocity are permitted. The solute concentration profile is greatly influenced by the periodic velocity fluctuations. The effectiveness of the explicit finite difference method for solving two-dimensional advection-diffusion equation with variable coefficients has been proven, which is especially important when arbitrary initial and boundary conditions are required.
