Abstract EN
In the present work, the natural convection heat transfer from horizontal cylinder with square cross section situated in a square enclosure, vented symmetrically from the top and the bottom is investigated experimentally.
The experimental work includes temperature measurements of the cylinder surface and the environment during transient state to determine Nu for the unbound and the bound cylinder.
The studied variable ranges were: 107 £ Ra £ 6.6´ 107 , 2 £ W/D £ 4, 0.25 £ O/D £ 4.
The results indicated an increase in Nu with increasing Ra.
Furthermore, Nu increased proportionally with the vent opening size at low enclosure widths.
It showed inverse proportionality with opening size for high enclosure widths.
The maximum percentage of the enhancement is more than 20% for bounded square cylinder as compared with unbounded square cylinder.
