“…Different levels of approximation in such mixed lumped-differential formulations can be used, starting from the plain and classical lumped system analysis, towards improved formulations, obtained through Hermite-type approximations for integrals [1,2]. Such approach has been already exploited in different heat and fluid flow problems [3][4][5][6][7][8][9][10], including phase change problems, extended surfaces (fins), anisotropic heat conduction, heat exchangers analysis, Navier-Stokes equations and drying problems themselves, and shall be reviewed within this section.…”
