The Green-Kubo representation of the shear viscosity of a dilute gas of inelastic hard disks derived from the Boltzmann equation is evaluated by means of the direct simulation Monte Carlo method. The relationship between the one-particle dynamics of the original expression and the N-particle ...

Thermal conductivity can be determined by molecular simulation through non-equilibrium and equilibrium means; the latter typically employs the Green–Kubo6,7 method, which can also be applied in the calculation of diffusion8 and viscosity9 too. By utilising the fluctuation dissipation and linear ...
A detailed comparison between two methods to calculate shear viscosity is presented. We choose two systems in this comparison which are massless particles with current algebra cross section and a mixture comprised of pions with rho resonances. The two methods involved are the Green-Kubo method, ...
The Green-Kubo representation of the shear viscosity of a dilute gas of inelastic hard disks derived from the Boltzmann equation is evaluated by means of the direct simulation Monte Carlo method. The relationship between the one-particle dynamics of the original expression and the N-particle ...
A Green-Kubo formula, relating the shear viscosity to discrete time correlation functions, is derived via a Liouville equation formalism for a class of non-deterministic lattice gas models. This allows a Monte-Carlo calculation of the viscosity. Preliminary results are presented for the Frisch-Hassl...
