A model of continuous, thermoelastic media within the frame of extended thermodynamics
The introduction of the heat flow vector and its spatial gradients as arguments in the Helmholtz free energy allows us to derive a new set of constitutive and kinetic equations describing thermoelastic interactions in continuous media. This set includes a generalized Fourier law for heat conduction that accounts for a finite velocity of propagation of thermal disturbances in the medium. Comparison is carried out with other existing models.
