Nonequilibrium entropy production under the effect of the dual-phase-lag heat conduction model

In the present work, the nonequilibrium entropy production under the effect of the dual-phase-lag heat conduction model is investigated. It is shown t hat the entropy production cannot be described using the classical form of the equilibrium entropy production where using this form leads to a violati on for the thermodynamics second law. The effect of the phase-lags in tempe rature and in heat flux on the nonequilibrium entropy production is investi gated. Also, the difference between the equilibrium and the nonequilibrium temperatures under the effect of the dual-phase-lag heat conduction model i s studied.
