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.engFluctuation-induced pressures in fluids in thermal nonequilibrium steady statesjournal articlehttp://dx.doi.org/10.1103/PhysRevE.89.022145http://arxiv.org/pdf/1401.1339v2.pdfhttp://journals.aps.org/open access536Asymptotic time behaviorTransport-coefficientsLight-scatteringConvective instabilityDiffusion-coefficientBurnett coefficientsNonlinear transportRayleigh-scatteringGiant fluctuationsPolymer-solutionTermodinámica2213 Termodinámica
