The Langevin NEMD method and the corresponding analysis workflow was validated on the basis of literature data for the mixture argon/krypton. The present Soret coefficient data (Figure ) agree well with data from literature, which were obtained using a broad variety of approaches: NEMD with synthetic NEMD simulations, 32;33 the heat exchange method, as well as the modified heat exchange method and reverse NEMD simulations and Green-Kubo-based EMD simulations. The average temperature that was observed in the central profile-fit region of our simulation volume varied with the imposed temperature difference. The colors on the depicted data points correspond to the observed relative temperature difference ∆T /T . It can be concluded that the present workflow is reliable but that it leaves some imprecision regarding the target temperature, which is on the order of 1 %.
