Perturbation technique with characteristics in convection‐dominated flows with small diffusion and dispersion
Huseyin Murat Cekirge, R.J. Fraga · Engineering Computations · 1986
The proposed method utilizes characteristics to model convection and perturbation technique for diffusion and dispersion. Thus, each physical process is treated by a numerical scheme well suited to it. The theory is treated in three dimensions and applied to a one‐dimensional problem. The objective of the paper is the improvement of numerical techniques used in enhanced oil recovery problems which involve convection‐dominated flows with small diffusion and dispersion.
