Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The phase behaviour of the restricted primitive model (RPM) is studied using
a microscopic approach recently developed for the description of phase
transitions in binary fluid mixtures. For the model we obtain the explicit expression
for the functional of the grand partition function. Based on the
functional we calculate the phase diagram of the RPM in the high temperature
approximation (HTA) and then we do this calculation taking into
account the terms of the higher orders in the effective Hamiltonian. In both
cases the phase diagrams demonstrate the gas-liquid (GL) and charge
ordering phase instabilities. In the latter case, the obtained value for the
GL critical temperature is in good agreement with the MC simulation data
whereas the critical density is underestimated. |
