Popis
Shrnutí:•Applications of modified variational iteration algorithms in oil pollution.•Numerical solution of diffusion equation arising in oil pollution.•Nonlinear initial value problems arise in science and ocean engineering.•A powerful and accurate method which provides a practical way of obtaining solutions of nonlinear partial differential equations .•Comparision with difference method, Adomian's decomposition method, multiquadric quasi-interpolation methods and LLWM. In this article, modified versions of variational iteration algorithms are presented for the numerical simulation of the diffusion of oil pollutions. Three numerical examples are given to demonstrate the applicability and validity of the proposed algorithms. The obtained results are compared with the existing solutions, which reveal that the proposed methods are very effective and can be used for other nonlinear initial value problems arising in science and engineering.
