Fitted Fourth Order Scheme for Singularly Perturbed Delay Convection-Diffusion Equations
Main Article Content
Abstract
This paper presents a fitted fourth order numerical scheme for solving singularly perturbedconvection-diffusion equations. The obtained scheme is transformed into a three-term recurrence relation and solved by Thomas algorithm. The stability and convergence of thepresent method have been investigated. The numerical results are presented by tables and graphs. The present method helps us to get good results and also to know the behavior ofthe solution in the boundary layer for perturbation parameter e is less than mesh size h.Moreover, the present method improves the findings of some existing numerical methods reported in the literature.
