A lattice mesoscopic model of dynamically heterogeneous fluids
A. Lamura, S. Succi
We introduce a mesoscopic three-dimensional Lattice Boltzmann Model which attempts to mimick the physical features associated with cage effects in dynamically heterogeneous fluids.…
Morphologies and flow patterns in quenching of lamellar systems with shear
Aiguo Xu, G. Gonnella, A. Lamura
We study the behavior of a fluid quenched from the disordered into the lamellar phase under the action of a shear flow. The dynamics of the system is described by Navier-Stokes and…
Finite difference lattice Boltzmann model with flux limiters for liquid-vapor systems
V. Sofonea, A. Lamura, G. Gonnella +1
In this paper we apply a finite difference lattice Boltzmann model to study the phase separation in a two-dimensional liquid-vapor system. Spurious numerical effects in macroscopic…
Helical polymer in cylindrical confining geometries
A. Lamura, T. W. Burkhardt, G. Gompper
Using an algorithm for simulating equilibrium configurations, we study a fluctuating helical polymer either (i) contained in a cylindrical pore or (ii) wound around a cylindrical r…
A lattice Boltzmann model with random dynamical constraints
A. Lamura, S. Succi
In this paper we introduce a modified lattice Boltzmann model (LBM) with the capability of mimicking a fluid system with dynamic heterogeneities. The physical system is modeled as…
Lattice Boltzmann model with hierarchical interactions
A. Lamura, S. Succi
We present a numerical study of the dynamics of a non-ideal fluid subject to a density-dependent pseudo-potential characterized by a hierarchy of nested attractive and repulsive in…
