Similarly, particle flux and drift velocity are related not only by the gradient of density but also by an additional contribution given by the gradient of the self-diffusion coefficient. We provide quantitative support to this scenario in a non-equilibrium system by means of computer simulations with a temperature gradient. Moreover, our simulation results demonstrate that the temperature gradient-induced mass transport coefficient, namely thermal diffusion coefficient, is not directly proportional to the drift velocity so that the well-accepted relation of proportionality is just an approximation. 000021323 536__ $$0G:(DE-Juel1)FUEK505$$2G:(DE-HGF)$$aBioSoft: Makromolekulare Systeme und biologische Informationsverarbeitung$$cP45$$x0 000021323 588__ $$aDataset connected to Web of Science, Pubmed 000021323 650_2 $$2MeSH$$aAlgorithms 000021323 650_2 $$2MeSH$$aComputer Simulation 000021323 650_2 $$2MeSH$$aDiffusion 000021323 650_2 $$2MeSH$$aModels, Chemical 000021323 650_2 $$2MeSH$$aSuspensions 000021323 650_2 $$2MeSH$$aThermodynamics 000021323 650_7 $$00$$2NLM Chemicals$$aSuspensions 000021323 650_7 $$2WoSType$$aJ 000021323 7001_ $$0P:(DE-Juel1)130920$$aRipoll, M.$$b1$$uFZJ 000021323 773__ $$0PERI:(DE-600)1473050-9$$a10.1063/1.4723685$$gVol. 136$$p204508$$q136$$tThe @journal of chemical physics$$v136$$x0021-9606$$y2012 000021323 8567_ $$uhttp://dx.doi.org/10.1063/1.4723685 000021323 8564_ $$uhttps://juser.fz-juelich.de/record/21323/files/FZJ-21323.pdf$$yPublished under German "Allianz" Licensing conditions on 2012-05-31.
