Comparison of some numerical methods for ozone decomposition of the second order in aqueous solutions

Abstract

A comparative study between optimal homotopy asymptotic method (OHAM) and some other well-known methods such as the Homotopy perturbation, Adomian decomposition and Runge-Kutta fehlberg fourth-fifth order methods has been presented in the current paper. These methods have been applied in solving the system of the second order decomposition of ozone in aqueous solutions. The obtained results indicate these methods are appropriate to solve the equations whereas applying OHAM is more simpler with the same accuracy in comparison to other methods.
