In this work we examine thermodynamics of fluid with "molecules" represented by two fused hard spheres, decorated by the attractive square-well sites. Interactions between these sites are of short-range and cause association ...

A multi-density version of the thermodynamic perturbation theory for associative fluids with central force associative potential is developed. The theory is used to describe the liquid-gas phase behavior of Stochmayer fluid ...

We propose an extension of the second-order Barker-Henderson perturbation theory for polydisperse hard-sphere multi-Morse mixture. To verify the accuracy of the theory, we compare its predictions for the limiting case of ...
