The method is based on splitting the convective and the diffusive differential terms thereby permitting an efficient scheme choice for each of them, and when combined give a reliable solution for the entire equation. We demonstrate the accuracy and capability of the proposed split scheme via several numerical experiments. Computations of the bound, $\displaystyle{\limsup_{t\rightarrow \infty}\|u(x,t)\|_2}$ for the equation is also presented.</p> ER -
