Symmetries and conservation laws for a subclass of lubrication equations by using free software. Rosa, M. Recio, M. The diffusion term can thus be rewritten as to yield:. Supercomputation in nonlinear and disordered systems. Nonlinear self-adjointness for a Fisher equation with a variable coefficients.

The Boussinesq approximation is a way to solve nonisothermal flow, such as natural convection problems, without having to solve for the full compressible formulation of the Navier-Stokes equations. It assumes that variations in density have no effect on the flow field, except that. TEORÍA L p. PARA EL SISTEMA DE BOUSSINESQ. Esta tesis está dedicada al estudio del .
