Abstract:

An implicit finite difference method is developed for a one-dimensional frac-tional percolation equation (FPE) with the Dirichlet and fractional boundary conditions. The stability and convergence are discussed for two special cases, i.e., a continued seep-age flow with a monotone percolation coefficient and a seepage flow with the fractional Neumann boundary condition. The accuracy and efficiency of the method are checked with two numerical examples.

Key words: finite difference method, frac-tional boundary condition, stability and convergence, Riemann-Liouville derivative, fractional percolation equation (FPE), Toeplitz matrix
