Variational Iteration Method for Solving Reaction Diffusion Equation in Oscillatory Chemical Reactions

A mathematical modelling of an oscillatory chemical reactions based on diffusion is discussed. Analytical solutions have been found for the system of nonlinear diffusion equations of second order in the model. Nonlinear oscillation partial differential equations can be solved accurately and efficiently using the He's variational iteration method. He's variational iteration method can be used to obtain approximate analytical solutions to the system. Analytical approximation is compared with numerical simulation as well.
