The connection between higher order fluxes in Extended Thermodynamics and those in Non-Equilibrium Thermo-dynamics with dynamic degrees of freedom is investigated on the example of rigid heat conductors. The conditions under which some extended thermodynamic models can be obtained by a dynamic variable theory are pointed out. Thermodynamic closure relations(More)
The role of gradient dependent constitutive spaces is investigated on the example of Extended Thermodynamics of rigid heat conductors. Different levels of nonlocality are developed and the different versions of extended thermodynamics are classified. The local form of the entropy density plays a crucial role in the investigations. The entropy inequality is(More)
The role of gradient dependent constitutive spaces is investigated on the example of Extended Thermodynamics of rigid heat conductors. Different levels of nonlocality are developed. The local form of the entropy density plays a crucial role in the investigations. The entropy inequality is solved under suitable additional assumptions. Balance form of(More)
