Diffusion of a liquid
This experiment aims to determine the diffusion coefficient of a liquid mixture, sodium chloride solution, in de-ionized water. We perform molecular dynamics (md) simulation of diffusion in liquid geo 2 at the temperatures ranged from 3000 to 5000 k and densities ranged from 365 to 790 g/cm 3.
