In this paper, the modified F-expansion method is proposed for constructing more than one
exact solutions of nonlinear convection diffusion equation with the aid of symbolic computation
Mathematica. By using this method, some new exact travelling wave solutions of the convection diffusion
equation are successfully obtained. These exact solutions include the soliton-like solutions, trigonometric
function solutions and rational solutions. Also, it is shown that the proposed method is efficient for
solving nonlinear partial differential equations arising in mathematical physics.
