Título: Sessile Drops: Spreading versus Evaporation-Condensation
Palestrante: Prof. Eliot Fried, McGill University, Montreal, Canada
Data: 13/05/2011; Horário: 14h; Local: CT, SALA G-205
Contato: Fernando Duda – duda@mecanica.ufrj.brAbstract:
The equations that govern the dynamics of the liquid-vapor interface and contact line of a sessile drop in the spreading and evaporation-condensation regimes are derived. During spreading, the liquid-vapor interface and contact line convect with the liquid and are therefore material. In contrast, when evaporation or condensation occurs, the liquid-vapor interface and contact line migrate relative to the liquid and are thus nonmaterial. For spreading, the evolution equations consist of kinematical constraints on the normal velocities of the liquid-vapor interface and contact line along with the normal and tangential components of the constitutively augmented standard force balances on the liquid-vapor interface and at the contact line. At equilibrium, the tangential components of the standard force balances on the liquid-vapor interface and contact line, being solely dissipative, are trivially satisfied. The normal component of the standard force balance on the liquid-vapor interface reduces to the Young-Laplace equation whereas its counterpart along the contact line simplifies to the generalization, accounting for line energy, of the Young equation mentioned by Gibbs. In the presence of evaporation-condensation, the kinematical constraints are no longer valid. Their absence is compensated for by the normal components of the configurational force balances on the liquid-vapor interface and contact line. Hence, away from equilibrium and in the presence of dissipation, a complete description of the liquid-vapor interface and contact line of a volatile drop involves the normal and tangential components of the standard force balances along with the normal components of the configurational force balances. At equilibrium, the normal component of the configurational force balance on the liquid-vapor interface simplifies to the condition for chemical equilibrium requiring the continuity of the chemical potential, whereas its counterpart along the contact line, being entirely dissipative, holds trivially. Comparison with recently proposed kinetic laws for the liquid-vapor interface and contact line of a nonvolatile drop is provided.

Contato: Fernando Duda – duda@mecanica.ufrj.brDuring the early 1950s, J.D. Eshelby developed a framework for the study of point, line, and surface defects in solids. Central to that framework is the notion of \emph{configurational force}. Whereas Newtonian forces are linked to the motion of material particles, configurational forces are associated with defects that may move with respect to material particles. Examples of such objects include impurities, dislocations, cracks, and phase interfaces. Eshelby’s approach involved a creative synthesis and extension of ideas appearing in J.L.\ Lagrange’s works on generalized coordinates and forces, J.W.\ Gibb’s works on the equilibrium of heterogeneous substances, J.\ Larmor’s works on the luminiferous \aether, and E.\ Noether’s works on conservation laws arising from the invariance of functionals. In Eshelby’s approach, the configurational force acting on a defect is determined by computing the variation of the total energy with respect to changes in the configuration of the defect. Eshelby’s contributions set the stage for many important contributions to the study of defects in solids, perhaps the most celebrated of these being to fracture, where the relevant configurational force acts at the tip of a crack and is the \emph{J-integral} derived independently by G.P.\ Cherepanov and J.R.\ Rice.
Being variational, Eshelby’s approach is predicated on the provision of constitutive relations. Further, it allows for (at most) infinitesimal departures from equilibrium and accounts only artificially for dissipative mechanisms which may accompany the motion of defects.
Beginning in the early 1990s, M.E.\ Gurtin constructed a theory that frees Eshelby’s framework from the foregoing restrictions. In keeping with the program for continuum mechanics set forth by B.D.\ Coleman and W.\ Noll, Gurtin’s approach delineates carefully between basic laws, which hold for large classes of materials, and constitutive relations, which distinguish between different materials. Configurational forces are treated as primitive and are assumed to obey a balance distinct from the conventional balances of linear and angular momentum. Further, power expenditures associated with the motion of defects are accounted for properly in the statement of the energy balance and, following Coleman and Noll, the entropy imbalance is used to determine physically reasonable restrictions on constitutive relations. A major advantage of Gurtin’s theory is that objects such as the \emph{J- integral} arise independent of constitutive assumptions and specialize not only to the standard elastic case but also to cases where inelastic effects are present.
In addition to giving an overview of the history of configurational forces, this course is intended to provide a flavor for the importance of configurational forces and the balance of configurational momentum in a variety of applications, including \emph{solidification} and \emph{disclinations in liquid crystals}. Moreover, whereas conventional treatments of configurational forces rely on a referential description, attention will be given to the spatial description of configurational forces.
