Abstract

Natural convection is
simulated in a truncated cone filled with Cu-water nanofluid,
pure water is considered as the base fluid with Pr=6.2 and  (Cu) is the 
nanoparticle  . Inclined and top walls have
constant temperature where the heat source is located on the bottom wall of the
conical container which is thermally insulated. A finite volume approach is
used to solve the governing equations using the SIMPLE algorithm for different
parameters such as Rayleigh number (10³, 10⁴, 10⁵
and 10⁶), inclination angle of inclined walls of the enclosure and
heat source length (0.3L, 0.7L and L). The results showed an
enhancement in cooling system by using a nanofluid, when conduction regime is
assisted. The inclination angle of inclined sidewall and heat source length
affect the heat transfer rate and the maximum temperature.
