Method of approximations for the convection-dominated anomalous diffusion equation in a rectangular plate using high-resolution compact discretization

open access: yesMethodsX, 2022
The present method describes the high-resolution compact discretization method for the numerical solution of the nonlinear fractal convection-diffusion model on a rectangular plate by employing the Hausdorff distance metric.

Numerical Simulation of Columnar Crystal/Equiaxed Crystal Formation Model in a Convection Diffusion-multiphase Transformation System

open access: yesCailiao gongcheng, 2017
The horizontal rapid solidification of Fe-Bi-Mn free-cutting alloys were simulated by using diffusion-governed phase transformation kinetics. The three-dimensional solidification model for a convection diffusion-multiphase transformation system was built.

Finite Difference Method for Two-Sided Two Dimensional Space Fractional Convection-Diffusion Problem with Source Term

open access: yesMathematics, 2020
In this paper, we have considered a numerical difference approximation for solving two-dimensional Riesz space fractional convection-diffusion problem with source term over a finite domain. The convection and diffusion equation can depend on both spatial
