“Crossover Equation of State: challenges for introducing density fluctuations into a cubic thermodynamic model.”
\nAbstract:
\n
\nThe development of a universal model to describe the thermodynamic properties of fluids over a wide range of temperatures and pressures is one the most difficult tasks of the theory of fluids.
Classical equations of state (EoS) are usually applied as a solution for this problem; however, since these models neglect the density fluctuations that arise near the critical point, they can only correctly represent the analytical behavior of fluids far from the critical region.
\nIn fact, a global description of a fluid, i.e. in regions both far away and close to the critical, requires a model that incorporates the effects of density fluctuations, being able to describe the singular behavior of fluids near the critical point, but also accounting for a crossover to the classical behavior in regions far from the critical.
\n
\nIn this seminar, an overview of a crossover EoS will be presented, as well as the challenges involved in the implementation of the model. Additionally, the appraisal of the model’s performance in relation to the traditional EoS will be given.
