Résumé :

The phase diagrams for fluids composed of spherical particles with a monomodal size distribution is presented. These phase diagrams are obtained on the basis of the van der Waals approximation for the free-energy of a polydisperse fluid. It is found that the largest modifications to the phase diagram of the polydisperse fluid, as compared to its monodisperse counterpart, result from the amplitude polydispersity of the interaction potential.
