摘要

An alternating-direction characteristic Galerkin method for 3-D compressible flow of contamination from nuclear waste in porous media is considered.Time-steping along the characteristics of hyperbolic part of the brine, radionuclide and heat equations is shown to result in smaller time-truncation errors than those resulting from standard methods. With an alternating-direction technique,a multidimensional problem can be solved as a series of one-dimensional problems. Optimal order H1-error estimates are derived.
