Numerical simulation of the coupled viscous Burgers equation using the Hermite formula and cubic B-spline basis functions

Abstract

A numerical procedure dependent on the cubic B-spline and the Hermite formula is developed for the coupled viscous Burgers' equation (CVBE). The method uses a combination of the Hermite formula and the cubic B-spline for discretization of the space dimension while the time dimension is approximated using the typical finite differences. A piecewise continuous sufficiently smooth function is obtained as a solution which allows to approximate solution at any location in the domain of interest. The scheme is tested for stability analysis and is proved to be unconditionally stable. Numerical experiments and comparison of outcomes reveal that the suggested scheme comes up with better accuracy and is extremely productive.
