Abstract: | In this study, a numerical investigation has been carried out to reveal the mechanism of fluid flow and heat transfer from
a vertical rectangular fin attached to a partially heated horizontal base. The problem is a conjugate conduction-convection
heat transfer problem with open boundaries. The governing equations for the problem are the conservation of mass, momentum
and energy equations for the fluid and the heat conduction equation for the fin. The control volume technique based on the
SIMPLEC algorithm with a nonstaggerred grid arrangement is employed to solve the governing equations. The effect of the heated
base, on the mechanism of the fluid flow and heat transfer, is numerically investigated. Temperature distribution and flow
patterns around the fin are plotted to support the discussion. Results are obtained for air at laminar and steady flow.
