Conservative Finite Difference Method for Solving Generalized BBM-KdV Equation
Publié 2022-08-01Accéder au texte intégralThe BBM-KdV equation plays an important role because it can describe a large number of physical phenomena, such as shallow water waves and ion waves. It is an important model for long-wave unidirectional propagation in weakly nonlinear dispersive media, but its numerical investigations are rarely ma...
