JIMOH, OMANANYI RAZAQ2025-04-222013-05-10http://www.akamaiuniversity.us/PJST.htmhttp://repository.futminna.edu.ng:4000/handle/123456789/870In this paper, we present a comparative analysis of non-reactive contaminant flow problem for constant initial concentration in two dimensions by homotopy-perturbation and Variational Iteration method. We provide an approximation of this equation using homotopy-perturbation transformation and solve the resulting linear equations analytically by homotopy-perturbation method (HPM) and Variational Iteration Method (VIM). Graphs are plotted using the solution obtained from the method and the results are presented and discussed.enHomotopy-perturbationcontaminantadvectiondiffusionadsorptionComparative Analysis of a Non-Reactive Contaminant Flow Problem for Constant Initial Concentration in Two Dimensions by Homotopy-Perturbation and Variational Iteration Methods.Article
