Transport coefficients in hard-sphere fluids: thermodynamic versus kinetic descriptions
Miguel Hoyuelos
A thermodynamic theory for transport coefficients in hard-sphere fluids is developed from a general expression for the Onsager matrix. The theory predicts the ratio ,…
A general thermodynamic approach for diffusion on a lattice
MatÃas A. Di Muro, Matías A. Di Muro, Miguel Hoyuelos
This work presents a general thermodynamic approach to describe particle diffusion on a lattice, a model used to study transport processes in solids and on surfaces. By treating ea…
A thermodynamic framework for the thermal conductivity of dense fluids
Miguel Hoyuelos
A thermodynamic framework that predicts the thermal conductivity of simple fluids beyond the dilute-gas limit is introduced. By generalizing the transition-rate approach of pa…
Transport with noise in dilute gases: Effect of Langevin thermostat on transport coefficients
Alejandro Alés, Juan Ignacio Cerato, Leandro Marchioni +1
In dilute gases, transport properties such as the thermal conductivity, self-diffusion, and viscosity are significantly affected by interatomic collisions, which are determined by…
Viscosity as the product of its ideal low-concentration value times a thermodynamic function
L. Marchioni, M. A. Di Muro, M. Hoyuelos
The behavior of viscosity, , as a function of concentration in dense fluids remains an unsolved problem, as is the case with other transport coefficients. Boltzmann's theory an…
Physical meaning of nonextensive term in Massieu functions
Miguel Hoyuelos, MatÃas A. Di Muro, Patricia Giménez
In this paper we explore the significance of nonextensive terms in Massieu functions. Finite-size effects are in many cases dominated by a term proportional to the surface area. Ne…
