An Eshelbian approach to the nonlinear mechanics of constrained solid-fluid mixtures
S. Quiligotti, G. Maugin, F. dell'Isola
Looking at rational mixture theories within the context of a new perspective, this work aims to put forward a proposal for an Eshelbian approach to the nonlinear mechanics of a con…
Nucleation of spherical shell-like interfaces by second gradient theory: numerical simulations
Francesco Dell'Isola, Henri Gouin, Giacomo Rotoli
The theory of second gradient fluids (which are able to exert shear stresses also in equilibrium conditions) allows us: (i) to describe both the thermodynamical and the mechanical…
Radius and surface tension of microscopic bubbles by second gradient theory
Francesco Dell'Isola, Henri Gouin, Pierre Seppecher
The classical theory of Laplace is not suitable for describing the behavior of microscopic bubbles. The theory of second gradient fluids (which are able to exert shear stresses in…
Bubble number in a caviting flow
Henri Gouin, Laurent Espanet
Cavitation is a general phenomenon of the fluid flows with obstacles. It appears in the cooling conduits of the fast nuclear engines. A model of this phenomenon using the theory of…
Hamiltonian Principle in Binary Mixtures of Euler Fluids with Applications to the Second Sound Phenomena
Henri Gouin, Tommaso Ruggeri
In the present paper we compare the theory of mixtures based on Rational Thermomechanics with the one obtained by Hamilton principle. We prove that the two theories coincide in the…
Compressible Fluids: the discontinuity of the vorticity vector on a shock wave in thermodynamical variables
Henri Gouin
The discontinuity of the vorticity is written as a function of the vector T grad s, (where T is the temperature and s the specific entropy). The expression is obtained thanks to po…
