Thermodynamical consistency of the Dual Phase Lag heat conduction equation

Abstract

Dual phase lag equation for heat conduction is analyzed from the point of view of non-equilibrium thermodynamics. Its first order Taylor series expansion is consistent with the second law as long as the two relaxation times are not negative.
