Abstract
Numerical solutions of the Korteweg de Vries–Burgers (KdVB) equation based on splitting is
studied. We put a real parameter into a KdVB equation and split the equation into two parts. The real
parameter that is inserted into the KdVB equation enables us to play with the splitted parts. The real
parameter enables to write the each splitted equation as close to the Korteweg de Vries (KdV) equation
as we wish and as far from the Burgers equation as we wish or vice a versa. Then we solve the splitted
parts numerically and compose the solutions to obtained the integrator for the KdVB equation. Finally
we present some numerical experiments for the solution of the KdV, Burger’s and KdVB equations. The
numerical experiments shows that the new splitting gives feasible and valid results.
