“…The latter is based on the construction of the equations of evolution for the two basic densities, namely, that of particles, n(r, i), and that of energy, e(j%t), and their fluxes of all orders, namely, the two vectorial ones, f n (r,i) and / å (ú%ß), and the tensorial ones, /J|"'(r,i) and I^(r,t) (where r = 2> 3,... indicates tensorial rank and also the order of the flux): This is described in detail in [26], see also [27][28][29][30][31][32][33]. These hydrodynamic fields are the average over the nonequilibrium ensemble of a corresponding set of dynamical variables that the closure procedure of equation (2) introduces [26].…”
