(author)We present a new plugin for LAMMPS for on-the-fly computation of transport properties (OCTP) in equilibrium molecular dynamics. OCTP computes the self- and Maxwell-Stefan diffusivities, bulk and shear viscosities, and thermal conductivities of pure fluids and mixtures in a single simulation. OCTP is the first implementation in LAMMPS that...journal article 2019

Jamali, S.H. (author), Wolff, L.W.M. (author), Becker, T. (author), Bardow, André (author), Vlugt, T.J.H. (author), Moultos, O. (author)Molecular Dynamics simulations were performed for the prediction of the finite-size effects of Maxwell-Stefan diffusion coefficients of molecular mixtures and a wide variety of binary Lennard-Jones systems. A strong dependency of computed diffusivities on the system size was observed. Computed diffusivities were found to increase with the...journal article 2018

Wolff, L.W.M. (author), Jamali, S.H. (author), Becker, T. (author), Moultos, O. (author), Vlugt, T.J.H. (author), Bardow, André (author)Mutual diffusion coefficients can be successfully predicted with models based on the Darken equation. However, Darken-based models require composition-dependent self-diffusion coefficients which are rarely available. In this work, we present a predictive model for composition-dependent self-diffusion coefficients (also called tracer diffusion...journal article 2018
