Design/methodology/approach - The solution domain is partitioned into uniform mesh. The collocation and the Galerkin methods where B-spline functions are used as base functions are applied to advection-diffusion equation. Findings - Given methods are unconditionally stable and the obtained results are comparable with some earlier studies in terms of accuracy. Originality/value - Quadratic and cubic B-spline base functions are used with Taylor series expansion for the discretization of the equation.eninfo:eu-repo/semantics/closedAccessCyberneticsDiffusionPolynomialsArticle40576277710.1108/03684921111142304Q1WOS:000294884200010N/A
