Exact solutions to nonlinear diffusion equations obtained by the decomposition method

摘要

In this paper, we develop a framework to obtain exact solutions to the nonlinear diffusion equations by employing the Adomian decomposition method. Exact solutions are obtained for some important physical processes of power law diffusivities. The method is capable of greatly reducing the size of computational domain and is presented in a general way so that it can be used in more diffusion classes.
