摘要
本文考虑空间分数阶对流-扩散方程(即在一个标准对流-扩散方程中,用分数阶导数代替空间二阶导数)混合问题的数值解,采用积分方法(有限体积方法)构造出它们的显式有限差分格式,并证明它们的稳定性和收敛性,最后给出数值例子。
We consider numerical solution of a space fractional advection- dispersion equation with mixed problem, which is obtained from the adveetion - dispersion equation by replacing the second order derivative in space by a fractional derivative in space of order. Using integration method or finite - volume method, we can give an explicit finite difference schemes for this equation. The stability and convergence of the finite difference sehemes are proved. Some numerical results are given.
