Abstract
The critical behaviour of an associating fluid mixture, the so called Lin-Taylor model, has been studied, with focus on the critical exponents which characterize different points on the critical manifold. In general the critical behaviour of the mixture is found to be Ising-like, but there are some special situations: when two ordinary critical points merge into a double critical point or three critical points coalesce at a critical inflection point. A check has been made on the validity of the relations between critical exponents and predictions from the scaling laws.File in questo prodotto:
