The MesoDyn project: software for mesoscale chemical engineering

We describe a new class of phenomenological mesoscopic models to simulate t he phase separation dynamics in three dimensional complex liquids, based on dynamic density functional methods. These models are generalizations of ti me-dependent Ginzburg-Landau models and contain a molecular description of the liquids in the free energy functional. Possible applications are in pro cess industries (HIPS, paints, detergents, surfactants,...), petroleum indu stries (oil recovery), pharmaceutical industries (drug delivery) and consum er product industries (food processing, cosmetics). We show the results of the simulation of the microphase behaviour of aqueous PL64 solutions. The w ork described here was mainly done within ESPRIT research projects funded b y the European Union.
