Information
The diffusion coefficient is calculated by a correlation from Fuller et al. [1], [2]. It calcuates the binary diffusion coeff. from the molar masses of the substances, the system pressure and temperature and the molecular diffusion volumes for the substances. The molecular diffusion volumes are calculated by summing the atomic contributions provided in [2].
