Heat diffusion in fractal geometry cooling surfaceRamšak, Matjaž (Avtor) Škerget, Leopold (Avtor) heat transfercooling of electronic devicesboundary element methodfractalsIn the paper the numerical simulation of heat diffusion in the fractal geometry of och snowflake is presented using multidomain mixed Boundary Element Method. he idea and motivation of work is to improve the cooling of small electronic devices sing fractal geometry of surface similar to cooling ribs. The heat diffusion is ssumed as the only principle of heat transfer. The results are compared to the heat lux of a flat surface. The limiting case of infinite small fractal element is computed sing Richardson extrapolation.20122015-07-10 12:37:20Znanstveno delo50230ISSN: 0354-9836UDK: 536OceCobissID: 43417089COBISS_ID: 16562710DOI: 10.2298/TSCI1204955RISSN pri članku: 0354-9836NUK URN: URN:SI:UM:DK:VDBUD39Rsl
