Language: | eng | Issue Date: | 14-Jun-2013 | Document Type: | Article | Journal / Series / Working Paper (HSU): | Chemical Physics Letters | Volume: | 574 | Page Start: | 37 | Page End: | 41 | Abstract: | The relaxation properties in the dilute-gas limit have been calculated by the classical trajectory (CT) method for a gas consisting of chain-like molecules that are rigid and interact through site-site Lennard-Jones 12-6 potentials. Results are reported for volume viscosity ηV, rotational collision number ζrot and the ratio of the rotational to self-diffusion coefficient Drot/D. The results indicate that the volume viscosity increases with temperature and decreases with chain length. The rotational relaxation of chains is efficient, as it takes of the order of 1.75-2.7 collisions to attain equilibrium. The rotational collision number is only weakly temperature dependent. © 2013 Elsevier B.V. All rights reserved. |
