Transport and Helfand moments in the Lennard-Jones fluid. II. Thermal conductivity.
نویسندگان
چکیده
The thermal conductivity is calculated with the Helfand-moment method in the Lennard-Jones fluid near the triple point. 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. The authors compute thermal conductivity by this new method and compare it with their own values obtained by the standard Green-Kubo method. The agreement is excellent.

Transport and Helfand moments in the Lennard-Jones fluid. I. Shear viscosity.
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 molecu...
متن کاملPredicting phonon properties and thermal conductivity from anharmonic lattice dynamics calculations and molecular dynamics simulations
Two methods for predicting phonon frequencies and relaxation times are presented. The first is based on quasiharmonic and anharmonic lattice dynamics calculations, and the second is based on a combination of quasiharmonic lattice dynamics calculations and molecular dynamics simulations. These phonon properties are then used with the Boltzmann transport equation under the relaxation-time approxi...
متن کاملThe Modified Lennard-Jones and Devonshire Equation of State
Lennard-Jones-Devonshire equation of state is an old but theoretical based EOS. The concept of the nearest neighboring molecules or coordination number is proposed to be a function of temperature and volume, whereas it is a constant in the original. The dilute gas and hard sphere limits of molecules are employed to determine this function. Improvement of this modification is demonstrated by pro...
متن کاملThermal Diffusion in Lennard-jones Fluids in the Frame of the Law of the Corresponding States
This work is related to the definition of a reduced thermal diffusion coefficient thanks to numerical microscale molecular dynamics simulations. This cross transport process, also called Soret effect, couples mass flux and thermal gradient and is still largely misunderstood. For this study, we have applied a boundary driven non equilibrium molecular dynamics algorithm on Lennard-Jones spheres m...
متن کاملPrediction of Fluid Mixture Transport Properties by Molecular Dynamics
Equilibrium molecular dynamics simulations of mixtures of n-decane with methane, ethane, and carbon dioxide and of the mixture carbon dioxide-ethane were performed using the anisotropic united atoms model for n-decane and oneand two-center Lennard-Jones models for the light components. The GreenKubo relations were used to calculate the viscosity, thermal conductivity, and interand intradiffusio...
