The paper presents nucleate boiling on the assembly with two-layer fins, composed of a copper core and capillary-porous structure (CPS) covering. The base heat flux for the fin assembly was determined. Two methods of heat flux calculation were described. The constants C and n in the formula[ q=C>T^n ] were determined experimentally on the basis of boiling curves. General relation for heat transfer coefficient was also used to specify the heat flux. Calculated heat fluxes were compared with experimental data for samples of different porosity (47-85%), CPS thickness (0.2-0.7 mm) and fins thickness (1.5-5 mm). A reasonable degree of congruence was found to exist between presented computation models and experimental results.
