Abstract
In this work, numerical solutions of the nonlinear coupled Burgers' equation with appropriate initial and boundary conditions in one space dimension are considered. A numerical method is proposed using the properties of uniform Haar wavelets together with a collocation method and based on semi-discretization along the space direction for solving a coupled viscous Burgers' equation. The semi-discretization scheme forms a system of nonlinear ordinary differential equations which is solved by the fourth-order Runge–Kutta method. Numerical experiments have been conducted in five examples to illustrate the merits of the proposed method. The relative errors and are computed from obtained numerical results. It is shown that the proposed method is working well and produces satisfactory results.
