Abstract
By using the long-wavelength approximation, a system of coupled evolut ion equations for the bulk velocity and the surface perturbations of a Benard-Marangoni system is obtained. It includes nonlinearity, disper sion, and dissipation, and it can be interpreted as a dissipative gene ralization of the usual Boussinesq system of equations. As a particula r case, a strictly dissipative version of the Boussinesq system is obt ained.
