| Abstract: | In this paper, the unsteady term in Burgers Equation is approximated by a simple difference formula, and the nonlinear term is linearized locally. Using exact Solution in local element for linearized equation, the Hybrid FAM schemes for solving Burgers Equation are established. Some theoretical properties of these schemes are proved. Several Numerical Examples are presented. The accuracy and stability of computational results are significanty good. |
