In modern numerical simulation of prospecting and exploiting oil-gas resources and environmental science, it is important to consider a numerical method for nonlinear convection-dominated diffusion problems. Based on actual conditions, such as the three-dimensional characteristics of large-scale sci

A ΓΏnite element methodology for obtaining non-oscillatory and non-di usive solutions to convection problems is proposed. The presented technique can be traced back to the concept of ux-corrected transport, but it di ers from the existing FEM-FCT methods in that the high-order solution is corrected p
In this paper, we propose a characteristics-mixed covolume method for approximating the solution to a convection dominated transport problem. The method is a combination of characteristic approximation to handle the convection term in time and mixed covolume method spatial approximation to deal with
