Abstract :
Natural convection of a nano
uid consisted of water and SiO2 in a square
enclosure cavity have been studied numerically. The sidewalls are maintained at di erent
constant temperatures and the other walls are thermally insulated. Two-phase mixture
model has been used to investigate the hydrodynamic and thermal behaviors of the
nano
uid for various inclination angles of enclosure ranging from = ??60 to = 60,
for Rayleigh numbers varying from 103 to 07 and for volume fraction = 0 ?? 6%. The
governing equations in a two-dimensional space are solved numerically using the nitevolume
approach. The results show that the average Nusselt number increases with
growth of both Rayleigh number and the volume fraction of the nanoparticles. Moreover,
inclination angle can be a control parameter for nano
uid lled enclosure, and the angle, in
which the maximum average Nusselt number occurs for various values of Rayleigh numbers
and volume fraction, is obtained
