Maximum Entropy Principle And Energy Dissipation Through Permeable Breakwaters

Abstract

By referring to the simplified schematization of monochromatic wave motion and of a permeable rectangular breakwater of constant porosity, an analysis is presented of the law which characterises energy dissipation inside a porous media. The problem was tackled both by adopting the theoretical approach of classical hydrodynamics, expressed in the definition and solution of differential equations of continuity, momentum and energy, and by using the maximum entropy principle. The latter approach, the results of which are very close to those of the former, has the advantage of introducing fewer parameters to calculate in the analytical formulas.
