The governing equations were solved using a Finite Volume Methodology (FVM). The computational domain was discretized using a uniform Cartesian grid with the appropriate mesh size along the x and y directions employing the corresponding number of grid points. The field variables were discretized at the cell centres and the spatial, as well as the time, derivatives were approximated using the second-order accurate numerical scheme. The time-evolution of the temperature and concentration fields, as well as the atomic diffusion coefficient, will be presented for the appropriate Al-Au nano-foil geometry and boundary conditionsV delu je predstavljena možnost numeričnega modeliranja z uporabo računske dinamike fluidov (CFDC) v primeru nanofolij. Ustrezne enačbe so bile rešene z uporabo metodologije končnih prostornin (FVM). Področje izračunov je bilo opredeljeno z uporabo enakomerne kartezijeve mreže s primerno velikostjo vzdolž smeri x in y z ustreznim številom mrežnih točk. Spremenljivke polj so bile opredeljene za središče celic in prostorske ter časovne derivative ter aproksimirane z uporabo numerične sheme z drugim redom velikosti natančnosti. Časovni razvoj temperaturnih in koncentracijskih polj in koeficient atomske difuzije sta predstavljena za ustrezno geometrijo Al-Au-nanofolij in mejne pogojeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
