In this article, the iterative transformation method and homotopy perturbation are applied to calculate solution of time-fractional Cauchy-reaction diffusion equations. technique, Shehu is combined iteration techniques. Four examples examined show validation efficacy present methods. The approximate solutions achieved by suggested methods indicate that approach easy apply given problems. Moreov...

In order to increase the rate of gas absorption, chemical reaction in the liquid phase is considered. The purpose of this paper was to simulate gas absorption process by a liquid film over a spherical packing incorporating eddy viscosity and diffusivity. Second order chemical reaction for two different cases (fast and slow) were considered. The system partial differential equations obtained...
