ABSTRACT: This study provided a new configuration of
the 180-deg round turned channel with a perforated divider, as well as numerically
investigated the effect of perforations, including the diameter of perforation
and the angel of perforation, on the fluid flow and heat transfer. The
numerical results appeared in good agreement with previous experimental data
under the same operating conditions. The results indicated that large size and
positive angle of perforation changed the fluid flow pattern and the local
Nusselt-number distribution fundamentally. It is noteworthy that a more uniform
distribution of Nusselt-number was achieved by increasing the diameter of
perforation.
