RANGEL-HUERTA, A.  and  CARRILLO, J.L.. Modelo hidrodinamico del termotransporte de electrones fuera de equilibrio en metales. Rev. mex. fis. [online]. 2002, vol.48, n.3, pp.219-227. ISSN 0035-001X.

We present a semiclassical kinetic model to describe a nonequilibrium metal gas electrons. By means of the Grad method of moments, we solve the modified Boltzmann transport equation in the scheme of the Lorentz-Sommerfeld theory. The non conserved balance equations for the electric current density and the heat flux are used to describe the main relaxation processes and the frequency dependent thermoelectric coefficients. A relevant characteristic of these coefficients are the presence of some kinetic relaxation times expressed through the Fermi-Dirac integrals.

Keywords : Kinetic theory; electron gases; thermoelectric effects.
