Onsager symmetry principle for a particle moving through a fluid not in equilibrium Rubí Capaceti, José Miguel Pérez Madrid, Agustín Fluctuacions (Física) Termodinàmica del desequilibri Fluctuations (Physics) Nonequilibrium thermodynamics We have shown that the mobility tensor for a particle moving through an arbitrary homogeneous stationary flow satisfies generalized Onsager symmetry relations in which the time-reversal transformation should also be applied to the external forces that keep the system in the stationary state. It is then found that the lift forces, responsible for the motion of the particle in a direction perpendicular to its velocity, have different parity than the drag forces. 2009-10-06T08:56:32Z 2009-10-06T08:56:32Z 1991 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1050-2947 https://hdl.handle.net/2445/9537 65226 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevA.43.7040 Physical Review A, 1991, vol. 43, núm. 12, p. 7040-7042. http://dx.doi.org/10.1103/PhysRevA.43.7040 (c) The American Physical Society, 1991 info:eu-repo/semantics/openAccess 3 p. application/pdf The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
