The time evolution of a homogeneous bidisperse granular suspension is studied in the context of the Enskog kinetic equation. The influence of the surrounding viscous gas on the solid particles is modeled via a deterministic viscous drag force plus a stochastic Langevin-like term. It is found first that, regardless of the initial conditions, the system reaches (after a transient period lasting a few collisions per particle) a universal unsteady hydrodynamic regime where the distribution function… 
Kinetic theory of granular particles immersed in a molecular gas
The transport coefficients of a dilute gas of inelastic hard spheres immersed in a molecular gas are determined. We assume that the number density of the granular gas is much smaller than that of the


Homogeneous steady states in a granular fluid driven by a stochastic bath with friction
The homogeneous state of a granular flow of smooth inelastic hard spheres or disks described by the Enskog–Boltzmann kinetic equation is analyzed. The granular gas is fluidized by the presence of a
Enskog kinetic theory for multicomponent granular suspensions.
The results show that the dependence of the transport coefficients on inelasticity is clearly different from that found in its granular counterpart (no gas phase), and previous theoretical results for dilute multicomponent granular suspensions are extended to higher densities.
Homogeneous states in driven granular mixtures: Enskog kinetic theory versus molecular dynamics simulations.
Comparison between kinetic theory and computer simulations for the temperature ratio shows excellent agreement, even for moderate densities and strong dissipation, and good agreement is found for the lower densities although significant discrepancies between theory and simulation are observed with increasing density.
Universal reference state in a driven homogeneous granular gas.
We study the dynamics of a homogeneous granular gas heated by a stochastic thermostat, in the low density limit. It is found that, before reaching the stationary regime, the system quickly "forgets"
Monte Carlo simulation of the homogeneous cooling state for a granular mixture
Abstract The Direct Simulation Monte Carlo (DSMC) method is used to numerically solve the Enskog equation for a granular binary mixture in the homogeneous cooling state (HCS). The fourth velocity
Simple shear flows of dilute gas–solid suspensions
Kinetic theory and numerical simulations are used to explore the dynamics of a dilute gas–solid suspension subject to simple shear flow. The particles experience a Stokes drag force and undergo
Rheology of a dilute binary mixture of inertial suspension under simple shear flow
The rheology of a dilute binary mixture of inertial suspension under simple shear flow is analyzed in the context of the Boltzmann kinetic equation. The effect of the surrounding viscous gas on the
Aging to non-Newtonian hydrodynamics in a granular gas
The evolution to the steady state of a granular gas subject to simple shear flow is analyzed by means of computer simulations. It is found that, regardless of its initial preparation, the system
Kinetic theory of shear thickening for a moderately dense gas-solid suspension: From discontinuous thickening to continuous thickening.
Comparison between theory and simulations indicates that while the theoretical predictions for the kinetic temperature agree well with simulations for densities φ≲0.5, the agreement for the other rheological quantities is limited to more moderate densities if the inelasticity during collisions between particles is not large.
Thermal diffusion segregation in granular binary mixtures described by the Enskog equation
The diffusion induced by a thermal gradient in a granular binary mixture is analyzed here in the context of the (inelastic) Enskog equation. Although the Enskog equation neglects velocity
