EXPONENETIAL AND LOGARITHMIC CRANK-NICOLSON METHODS FOR SOLVINGCOUPLED BURGER’S EQUATIONS

In this paper we apply a new methods called exponential and logarithmicCrank-Nicolson methods for solving a coupled of Burgers equations. Thesemethods are shown that the stability and accuracy are better than of the exponentialand logarithmic finite difference methods for long time. Error norms L2 and L∞show that the present methods are a successful numerical schemes for solving acoupled Burgers’ equations.
