Introduction, to predict these anomalous heat conductions. This chapter reviews the present non-Fourier heat conduction theories. For ultrafast heat conduction, modification models such as the Cattaneo–Vernotte model, dual phase lag model, and hyperbolic two-step model are developed. The common feature of these

General Entropy Production Based on Dynamical Analysis, with the classical entropy expression gives a non-quadratic form, which needs to be mended to avoid the paradox of negative entropy production. Based on the thermomass theory, it is shown that the entropy production corresponds to the dissipation of the mechanical energy of thermomass flow. Therefo

Nonequilibrium Temperature in Non-Fourier Heat Conduction,o be compatible with the non-Fourier heat conduction, the nonequilibrium temperature is defined. Based on the thermomass theory, it is shown that the static and stagnant pressures of the thermomass flow correspond to the static and stagnant temperatures, respectively. The stagnant temperature is hig

In this chapter, the unambiguous definition of the generalized forces and fluxes in the entropy production is presented from the thermomass viewpoint. The linear regressi

Dynamical Analysis of Heat Conduction in Nanosystems and Its Application, as a result of the phonon-boundary scattering. It is proposed in this chapter that the phonon gas (the form of thermomass in dielectric materials) exhibits the viscosity and rarefication effects in nanosystems. The viscosity effect induces the nonuniform heat flux profile at each cross section, whi
