In this paper, we present a solution based on Crank-Nicolson finite difference method for one-dimensional Burgers’ equation. Burgers’ equation arises frequently in mathematical modeling of problems in fluid dynamics. Hopf-Cole transformation [E. Hopf, The partial differential equation ut + uux = νuxx, Commun. Pure Appl. Math. 3 (1950) 201–230, J.D. Cole, On a quasilinear parabolic equation occurring in aerodynamics, Quart. Appl. Math. 9 (1951) 225–236] is used to linearize Burgers’ equation, the resulting heat equation is discretized by using Crank-Nicolson finite difference scheme. This method is shown to be unconditionally stable and second order accurate in space and time. Numerical results obtained by the present method have been compared with exact solution for different values of Reynolds’ number.
