Thermodynamic perturbation theory for central-force associating potentials and Monte Carlo simulations are used to study the phase behaviour of the dipolar Yukawa hard-sphere fluid over a wide range of the particle dipole moment, μ. Liquid-vapour coexistence is found to exist for values of μ far in excess of a “threshold” value found in earlier simulation studies. The predictions of the present theory are found to be in reasonably good agreement with computer simulation results, all the way up to the highest dipole moment studied.
