摘要: A shock-capturing technique is introduced for a finite element approach of the governing balance equations flow, contaminant mass and heat transport in variably saturated porous media. It represents nonlinear method which depends itself on numerical solution characterized by an additional discontinuity-capturing term controlling derivatives direction gradient. The embedded predictor-corrector scheme first second order time to handle implicitly. impact studied selected applications.
