Abstract
Laminar natural convection in vertical
enclosures with conducting fins attached to the hot
vertical wall has been studied numerically. Side
vertical walls were kept at constant but different
temperatures, while the horizontal top and bottom
walls were kept adiabatically. A conjugate
formulation was used for the mathematical
formulation of the problem and a computer program
based on the control volume approach and the
SIMPLEC algorithm was used. The main aim of the
current paper is to study numerically the effects of
the number of fins and fins length as well as
Rayleigh number on the flow pattern and heat
transfer. It was observed that the heat transfer rate
through an enclosure is affected greatly and hence
can be controlled by the number of the attached fins
to the vertical side wall of the enclosure as well as
the fin lengths.
