Study of Natural Convection in a Horizontal Square Enclosure with 4-Inner Heated Rods
Keywords:
Natural convection, square enclosure, penaltyAbstract
Laminar, natural convection heat transfer of air filling horizontal space betweenisothermal (cold) square enclosure and four isothermal (hot) cylindrical rods has been
theoretically studied. Finite element method has been used to solve the conservation of
governing equations by using software package (FlexPDE).
Parametric study has been conducted for the range of Rayliegh number10
,
Aspect ratio 0.11AR0.28. Results are presented in the form of streamlines, isotherms
contours and Nusselt numbers. Results showed that the overall heat transfer increases with
increasing of both Ra and AR. The values of mean Nusselt numbers are compared with data
reported in Ref.
[6]
and
[15]
, and good agreement has been achieved.
