The Cummings-Stell model of associative fluids : a general solution

In a series of publications the Cummings-Stell model (CSM), for a binary mixture of associative fluids with steric effects, has been solved analytically using the Percus-Yevick approximation (PYA). The solution consists in a square well potential of width w, whose center is placed into the hard sphere shell (r < σ): at L = σ/n (n = 1, . . . , 4). This paper… CONTINUE READING
