We present a numerical study of a stabilization method for computing confined and free-surface flows of highly elastic viscoelastic fluids. In this approach, the constitutive equation based on the conformation tensor, which is used to define the viscoelastic model, is modified introducing an evolution equation for the square-root conformation tensor. Both confined and free-surface flows are con...

Porous solids used in practical applications often possess structural disorder over broad length scales. This strongly affects different properties of the substances confined their pore spaces. Quantifying and correlating it with physical matter is thus a necessary step toward rational use porous process optimization. The present work focuses on recent advances made understanding correlations b...

Abstract The balance of pseudomomentum is discussed and applied to simple elasticity, ideal fluids, the mechanics inextensible rods sheets. A general framework presented in which simultaneous variation an action with respect position, time, material labels yields bulk laws jump conditions for momentum, energy, pseudomomentum. example elasticity space-filling solids treated at length. fluids sho...

The interfacial and structural properties of fluids confined by surfaces of different geometries are studied at the mesoscopic scale using dissipative particle dynamics simulations in the grand canonical ensemble. The structure of the surfaces is modeled by a simple function, which allows us to simulate readily different types of surfaces through the choice of three parameters only. The fluids ...
