Modélisation et simulation de la Formation des Nanocapsules polymériques par la méthode d'émulsion-diffusion

Abstract : The main objective of this work is the comprehension and modeling of the mechanism of the polymeric nanocapsule formation by emulsion diffusion method.
In this work we present a model of phases separation coupled with mass transfer for an open system. The proposed approach is based on the concept of local equilibrium. In this model, the phase separation is treated locally by using a preliminary test of stability based on Gibbs tangent plane criterion. This method is able to predict precisely the phase stability for a given volume dV and in the case of instability; to gives the exact number and composition of phases.
And to describe the mass transfer, the mass balance equation, the molar flux and thermodynamic balance are established on each volume. The Flux of transfer of all the components are described by the diffusion model developed by Fornasiero and the mass transfer at the interface is described by the film model.
