Thermodynamics of Interfaces and Fluid Mechanics deals with interfaces that are space areas with a low thickness and which separate environments of different properties. They designate phase separation but also thin flames and waves of discontinuity. At a macroscopic scale, they are associated with material surfaces that possess thermodynamic attributes and their own behavior laws.
The analysis of systems with interfaces involves scale changes and the use of specific techniques such as asymptotic developments, the second gradient theory or the phase field model method. Digital simulation is implemented in order to solve the complex systems studied. Testing is an essential step to solve the set problems.
2D varieties of interfaces often coexist with 1D varieties such as ligaments (atomization), contact lines (set drops) or Plateau’s edges (foams).
The articles in the journal deal with all of the mentioned above subjects.
Thermodynamique des interfaces et mécanique des fluides traite des interfaces qui sont des zones de l’espace de faible épaisseur séparant des milieux à propriétés différentes. Elles désignent les séparations de phase, mais aussi les flammes minces et les ondes de discontinuité. A l’échelle macroscopique, on les assimile à des surfaces matérielles douées de propriétés thermodynamiques et possédant leurs propres lois de comportement.
L’analyse des systèmes comprenant des interfaces implique des changements d’échelle et l’utilisation de techniques spécifiques telles que les développements asymptotiques, la théorie du second gradient ou la méthode des champs de phase. La simulation numérique est mise en œuvre pour résoudre les systèmes complexes étudiés. L’expérimentation est une étape indispensable pour résoudre les problèmes posés.
Les variétés 2D que constituent les interfaces coexistent fréquemment avec des variétés 1D telles les ligaments (atomisation), les lignes de contact (gouttes posées) ou les bords de Plateau (mousses).
Les articles de la revue traitent de l’ensemble des disciplines énumérées plus haut.
This work is devoted to a theoretical analysis of evaporating mass frequency response to pressure oscillations of a spray of repetitively injected drops into a combustion chamber. A single stationary spherical droplet (...)
We examine cases of stationary vortices that can appear inside spherical liquid drops. The first case is that of an incompressible external flow of uniform speed at infinity, leading the liquid in the drop by friction to (...)
In this short article, we give a summary of combustion-based weapons and their effects. Flame throwers and thermobaric weapons, bombs: napalm, explosive devices, phosphorus bombs are mentioned. Then it comes to missiles, (...)
The macroscopic balance equations of the fluid interfaces were established by considering two scales of length and by means of some approximations, such as the conservation of the mixed velocity vector and of the gradient (...)
The simulation engine system is an important issue in the automotive industry because of speeding up the design process, and limit the use of physical prototypes testing. The platform AMESim allows to access to libraries (...)
