Applying volume averaging theory (VAT) to a system of transport equations, a heat-sink structure was modeled as a homogeneous porous medium. The geometry of the simulation domain and the boundary conditions followed the experimental setup used in the Morrin-Martinelly-Gier Memorial Heat Transfer Laboratory at the University of California, Los Angeles. The example numerical simulations were performed for the test section with an isothermal structure as well as for the heat-conducting aluminium pin-fins. A comparison of the whole-section drag coefficient Cd as a function of Reynolds number Reh revals good agreement with existing data, whereas the comparison of the Nusselt number Nu distributions shows larger discrepancies. The finite conductivity of the solid decreases the heat-transfer coefficient and Nusselt number Nu. The influence of conductivity becomes larger with increasing Reynolds number"},{"@xml:lang":"sl","#text":"Prispevek opisuje razvoj algoritma za izračun vezanega prenosa toplote z namenom izbire najugodnejše geometrijske oblike za hladilnik elektronskega čipa.
