Surface tension at the liquid-vapor interface of screened ionic mixtures
The liquid-vapor interface of binary mixtures of charged particles is studied using molecular dynamics (MD) simulations. The interaction between particles is given by a short-range repulsive potential plus an attractive/repulsive Yukawa term, which models screened electrostatic interactions. To o...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The liquid-vapor interface of binary mixtures of charged particles is studied
using molecular dynamics (MD) simulations. The interaction between particles
is given by a short-range repulsive potential plus an attractive/repulsive
Yukawa term, which models screened electrostatic interactions. To obtain
the components of the pressure tensor two methods were used: a hybrid
MD method which combines the hard sphere and continuous forces and
a standard continuous MD method where the hard sphere was replaced
by a soft interaction. We show that both models give essentially the same
results. As the range of interaction decreases, the critical temperature and
surface tension increase. The comparison with the restricted primitive model
of ionic fluids is discussed. |
