In this study, Gegenbauer wavelets are used to present two numerical methods for solving
the coupled system of Burgers’ equations with a time-fractional derivative. In the presented methods,
we combined the operational matrix of fractional integration with the Galerkin method and the
collocation method to obtain a numerical solution of the coupled system of Burgers’ equations with a
time-fractional derivative. The properties of Gegenbauer wavelets were used to transform this system
to a system of nonlinear algebraic equations in the unknown expansion coefficients. The Galerkin
method and collocation method were used to find these coefficients. The main aim of this study was to
indicate that the Gegenbauer wavelets-based methods is suitable and efficient for the coupled system
of Burgers’ equations with time-fractional derivative. The obtained results show the applicability and
efficiency of the presented Gegenbaur wavelets-based methods.
