RT Journal Article T1 Fluctuation-induced pressures in fluids in thermal nonequilibrium steady states A1 Kirkpatrick, T. R. A1 Ortiz De Zárate Leira, José María A1 Sengers, J. V. AB Correlations in fluids in nonequilibrium steady states are long range. Hence, finite-size effects have important consequences in the nonequilibrium thermodynamics of fluids. One consequence is that nonequilibrium temperature fluctuations induce nonequilibrium Casimir-like pressures proportional to the square of the temperature gradient. Hence, fluctuations cause a breakdown of the concept of local thermal equilibrium. Furthermore, transport coefficients become dependent on boundary conditions and on gravity. Thus nonequilibrium fluctuations affect some traditional concepts in nonequilibrium thermodynamics.
