One-dimensional Janus fluids. Exact solution and mapping from the quenched to the annealed system
M. A. G. Maestre, A. Santos
The equilibrium properties of a Janus fluid confined to a one-dimensional channel are exactly derived. The fluid is made of particles with two faces (active and passive), so that t…
Random Walks on Lattices. Influence of Competing Reaction Centers on Diffusion-Controlled Processes
E. Abad, T. Abil, A. Santos +1
We study diffusion-reaction processes on periodic square planar lattices and simple cubic (sc) lattices. Considered first is a single diffusing reactant undergoing an irreversible…
Structure of the square-shoulder fluid
S. B. Yuste, A. Santos, M. López de Haro
The structural properties of square-shoulder fluids are derived from the use of the rational function approximation method. The computation of both the radial distribution function…
Solutions of the moment hierarchy in the kinetic theory of Maxwell models
Andrés Santos
In the Maxwell interaction model the collision rate is independent of the relative velocity of the colliding pair and, as a consequence, the collisional moments are bilinear combin…
Alternative Approaches to the Equilibrium Properties of Hard-Sphere Liquids
M. Lopez de Haro, S. B. Yuste, A. Santos
An overview of some analytical approaches to the computation of the structural and thermodynamic properties of single component and multicomponent hard-sphere fluids is provided. F…
DSMC evaluation of the Navier-Stokes shear viscosity of a granular fluid
J. M. Montanero, A. Santos, V. Garzo
A method based on the simple shear flow modified by the introduction of a deterministic non-conservative force and a stochastic process is proposed to measure the Navier-Stokes she…
Demixing can occur in binary hard-sphere mixtures with negative non-additivity
A. Santos, M. Lopez de Haro
A binary fluid mixture of non-additive hard spheres characterized by a size ratio and a non-additivity parameter is considered in infinitely m…
The penetrable-sphere fluid in the high-temperature, high-density limit
L. Acedo, A. Santos
We consider a fluid of -dimensional spherical particles interacting via a pair potential which takes a finite value if the two spheres are overlapped () and 0 ot…
Exact steady state solution of the Boltzmann equation: A driven 1-D inelastic Maxwell gas
A. Santos, M. H. Ernst
The exact nonequilibrium steady state solution of the nonlinear Boltzmann equation for a driven inelastic Maxwell model was obtained by Ben-Naim and Krapivsky [Phys. Rev. E 61, R5…
Equation of state of additive hard-disk fluid mixtures: A critical analysis of two recent proposals
M. Lopez de Haro, S. B. Yuste, A. Santos
A detailed analysis of two different theoretical equations of state for a binary mixture of additive hard disks [C. Barrio and J. R. Solana, Phys. Rev. E 63, 011201 (2001); A. Sant…
On the derivation of a high-velocity tail from the Boltzmann-Fokker-Planck equation for shear flow
L. Acedo, A. Santos, A. V. Bobylev
Uniform shear flow is a paradigmatic example of a nonequilibrium fluid state exhibiting non-Newtonian behavior. It is characterized by uniform density and temperature and a linear…
Non-Newtonian Poiseuille flow of a gas in a pipe
Mohamed Tij, Andrés Santos
The Bhatnagar-Gross-Krook kinetic model of the Boltzmann equation is solved for the steady cylindrical Poiseuille flow fed by a constant gravity field. The solution is obtained as…
Monte Carlo simulation of a hard-sphere gas in the planar Fourier flow with a gravity field
E. E. Tahiri, M. Tij, A. Santos
By means of the Direct Simulation Monte Carlo method, the Boltzmann equation is numerically solved for a gas of hard spheres enclosed between two parallel plates kept at different…
On the influence of gravity on the thermal conductivity
M. Tij, V. Garzó, A. Santos
In this paper we evaluate the corrections to the Navier-Stokes constitutive equations induced by the action of a gravitational field in a gas subjected to a thermal gradient parall…
Demixing in binary mixtures of hard hyperspheres
S. B. Yuste, A. Santos, M. López de Haro
The phase behavior of binary fluid mixtures of hard hyperspheres in four and five dimensions is investigated. Spinodal instability is found by using a recent and accurate prescript…
