Abstract = {{The reverse nonequilibrium molecular dynamics (RNEMD) method calculates |
| 14 |
the shear viscosity of a fluid by imposing a nonphysical exchange of |
| 15 |
momentum and measuring the resulting shear velocity gradient. In this |
| 16 |
study we investigate the range of momentum flux values over which RNEMD |
| 17 |
yields usable (linear) velocity gradients. We find that nonlinear |
| 18 |
velocity profiles result primarily from gradients in fluid temperature |
| 19 |
and density. The temperature gradient results from conversion of heat |
| 20 |
into bulk kinetic energy, which is transformed back into heat elsewhere |
| 21 |
via viscous heating. An expression is derived to predict the |
| 22 |
temperature profile resulting from a specified momentum flux for a |
| 23 |
given fluid and simulation cell. Although primarily bounded above, we |
| 24 |
also describe milder low-flux limitations. RNEMD results for a |
| 25 |
Lennard-Jones fluid agree with equilibrium molecular dynamics and |
| 26 |
conventional nonequilibrium molecular dynamics calculations at low |
| 27 |
shear, but RNEMD underpredicts viscosity relative to conventional NEMD |
| 28 |
at high shear.}}, |

Abstract = {{The reverse nonequilibrium molecular dynamics method for thermal |
| 138 |
conductivities is adapted to the investigation of molecular fluids. The |
| 139 |
method generates a heat flux through the system by suitably exchanging |
| 140 |
velocities of particles located in different regions. From the |
| 141 |
resulting temperature gradient, the thermal conductivity is then |
| 142 |
calculated. Different variants of the algorithm and their combinations |
| 143 |
with other system parameters are tested: exchange of atomic velocities |
| 144 |
versus exchange of molecular center-of-mass velocities, different |
| 145 |
exchange frequencies, molecular models with bond constraints versus |
| 146 |
models with flexible bonds, united-atom versus all-atom models, and |
| 147 |
presence versus absence of a thermostat. To help establish the range of |
| 148 |
applicability, the algorithm is tested on different models of benzene, |
| 149 |
cyclohexane, water, and n-hexane. We find that the algorithm is robust |
| 150 |
and that the calculated thermal conductivities are insensitive to |
| 151 |
variations in its control parameters. The force field, in contrast, has |
| 152 |
a major influence on the value of the thermal conductivity. While |
| 153 |
calculated and experimental thermal conductivities fall into the same |
| 154 |
order of magnitude, in most cases the calculated values are |
| 155 |
systematically larger. United-atom force fields seem to do better than |
| 156 |
all-atom force fields, possibly because they remove high-frequency |
| 157 |
degrees of freedom from the simulation, which, in nature, are |
| 158 |
quantum-mechanical oscillators in their ground state and do not |
| 159 |
contribute to heat conduction.}}, |

Abstract = {{Equilibrium molecular dynamics simulations have been carried out in the |
| 188 |
microcanonical ensemble at 300 and 255 K on the extended simple point |
| 189 |
charge (SPC/E) model of water {[}Berendsen et al., J. Phys. Chem. 91, |
| 190 |
6269 (1987)]. In addition to a number of static and dynamic properties, |
| 191 |
thermal conductivity lambda has been calculated via Green-Kubo |
| 192 |
integration of the heat current time correlation functions (CF's) in |
| 193 |
the atomic and molecular formalism, at wave number k=0. The calculated |
| 194 |
values (0.67 +/- 0.04 W/mK at 300 K and 0.52 +/- 0.03 W/mK at 255 K) |
| 195 |
are in good agreement with the experimental data (0.61 W/mK at 300 K |
| 196 |
and 0.49 W/mK at 255 K). A negative long-time tail of the heat current |
| 197 |
CF, more apparent at 255 K, is responsible for the anomalous decrease |
| 198 |
of lambda with temperature. An analysis of the dynamical modes |
| 199 |
contributing to lambda has shown that its value is due to two |
| 200 |
low-frequency exponential-like modes, a faster collisional mode, with |
| 201 |
positive contribution, and a slower one, which determines the negative |
| 202 |
long-time tail. A comparison of the molecular and atomic spectra of the |
| 203 |
heat current CF has suggested that higher-frequency modes should not |
| 204 |
contribute to lambda in this temperature range. Generalized thermal |
| 205 |
diffusivity D-T(k) decreases as a function of k, after an initial minor |
| 206 |
increase at k = k(min). The k dependence of the generalized |
| 207 |
thermodynamic properties has been calculated in the atomic and |
| 208 |
molecular formalisms. The observed differences have been traced back to |
| 209 |
intramolecular or intermolecular rotational effects and related to the |
| 210 |
partial structure functions. Finally, from the results we calculated it |
| 211 |
appears that the SPC/E model gives results in better agreement with |
| 212 |
experimental data than the transferable intermolecular potential with |
| 213 |
four points TIP4P water model {[}Jorgensen et al., J. Chem. Phys. 79, |
| 214 |
926 (1983)], with a larger improvement for, e.g., diffusion, |
| 215 |
viscosities, and dielectric properties and a smaller one for thermal |
| 216 |
conductivity. The SPC/E model shares, to a smaller extent, the |
| 217 |
insufficient slowing down of dynamics at low temperature already found |
| 218 |
for the TIP4P water model.}}, |

Transition metals can also be simulated using the embedded atom method (EAM) potential included in the code. Parallel simulations are carried out using the force-based decomposition method. Simulations are specified using a very simple C-based meta-data language.

Abstract = {{A nonequilibrium method for calculating the shear viscosity is |
| 267 |
presented. It reverses the cause-and-effect picture customarily used in |
| 268 |
nonequilibrium molecular dynamics: the effect, the momentum flux or |
| 269 |
stress, is imposed, whereas the cause, the velocity gradient or shear |
| 270 |
rate, is obtained from the simulation. It differs from other |
| 271 |
Norton-ensemble methods by the way in which the steady-state momentum |
| 272 |
flux is maintained. This method involves a simple exchange of particle |
| 273 |
momenta, which is easy to implement. Moreover, it can be made to |
| 274 |
conserve the total energy as well as the total linear momentum, so no |
| 275 |
coupling to an external temperature bath is needed. The resulting raw |
| 276 |
data, the velocity profile, is a robust and rapidly converging |
| 277 |
property. The method is tested on the Lennard-Jones fluid near its |
| 278 |
triple point. It yields a viscosity of 3.2-3.3, in Lennard-Jones |
| 279 |
reduced units, in agreement with literature results. |

Abstract = {{Atomistic simulations are conducted to examine the dependence of the |
| 306 |
viscosity of 1-ethyl-3-methylimidazolium |
| 307 |
bis(trifluoromethanesulfonyl)imide on temperature and water content. A |
| 308 |
nonequilibrium molecular dynamics procedure is utilized along with an |
| 309 |
established fixed charge force field. It is found that the simulations |
| 310 |
quantitatively capture the temperature dependence of the viscosity as |
| 311 |
well as the drop in viscosity that occurs with increasing water |
| 312 |
content. Using mixture viscosity models, we show that the relative drop |
| 313 |
in viscosity with water content is actually less than that that would |
| 314 |
be predicted for an ideal system. This finding is at odds with the |
| 315 |
popular notion that small amounts of water cause an unusually large |
| 316 |
drop in the viscosity of ionic liquids. The simulations suggest that, |
| 317 |
due to preferential association of water with anions and the formation |
| 318 |
of water clusters, the excess molar volume is negative. This means that |
| 319 |
dissolved water is actually less effective at lowering the viscosity of |
| 320 |
these mixtures when compared to a solute obeying ideal mixing behavior. |
| 321 |
The use of a nonequilibrium simulation technique enables diffusive |
| 322 |
behavior to be observed on the time scale of the simulations, and |
| 323 |
standard equilibrium molecular dynamics resulted in sub-diffusive |
| 324 |
behavior even over 2 ns of simulation time.}}, |

Abstract = {A nonequilibrium molecular dynamics method for calculating the thermal conductivity is presented. It reverses the usual cause and effect picture. The ''effect,'' the heat flux, is imposed on the system and the ''cause,'' the temperature gradient is obtained from the simulation. Besides being very simple to implement, the scheme offers several advantages such as compatibility with periodic boundary conditions, conservation of total energy and total linear momentum, and the sampling of a rapidly converging quantity (temperature gradient) rather than a slowly converging one (heat flux). The scheme is tested on the Lennard-Jones fluid. (C) 1997 American Institute of Physics.}, |

Abstract = {A novel non-equilibrium method for calculating transport coefficients is presented. It reverses the experimental cause-and-effect picture, e.g. for the calculation of viscosities: the effect, the momentum flux or stress, is imposed, whereas the cause, the velocity gradient or shear rates, is obtained from the simulation. It differs from other Norton-ensemble methods by the way, in which the steady-state fluxes are maintained. This method involves a simple exchange of particle momenta, which is easy to implement and to analyse. Moreover, it can be made to conserve the total energy as well as the total linear momentum, so no thermostatting is needed. The resulting raw data are robust and rapidly converging. The method is tested on the calculation of the shear viscosity, the thermal conductivity and the Soret coefficient (thermal diffusion) for the Lennard-Jones (LJ) fluid near its triple point. Possible applications to other transport coefficients and more complicated systems are discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.}, |

The Helfand moment of thermal conductivity is here derived for molecular dynamics with periodic boundary conditions. Thermal conductivity is given by a generalized Einstein relation with this Helfand moment.

Abstract = {The authors propose a new method, the Helfand-moment method, to compute the shear viscosity by equilibrium molecular dynamics in periodic systems. In this method, the shear viscosity is written as an Einstein-type relation in terms of the variance of the so-called Helfand moment. This quantity is modified in order to satisfy systems with periodic boundary conditions usually considered in molecular dynamics. They calculate the shear viscosity in the Lennard-Jones fluid near the triple point thanks to this new technique. They show that the results of the Helfand-moment method are in excellent agreement with the results of the standard Green-Kubo method. (C) 2007 American Institute of Physics.}, |
