Abstract
This study focuses on free convective flow and thermal behavior in a
two-dimensional closed enclosure with internal heat conductive body. Under
steady-state, laminar, and incompressible flow conditions, the finite element method
(FEM) is used to solve the governing equations for mass, momentum, and energy
conservation. The impact of important key parameters for Newtonian, water-based
Cu nanofluids (Pr = 7.0), namely, the Rayleigh number (104 ≤ Ra ≤ 107)
and nanoparticle volume percentage (0.01 ≤ φ ≤ 0.1) are analyzed in the present
work. The findings are expressed by streamlines for flow patterns, isotherms
for thermal distribution, and velocity as well as temperature profiles for
better understanding of the considered phenomena. In addition, heat transfer
rate at bottom wall is evaluated which is shown in terms of average Nusselt
number. Obtained results show that heat transfer rate is higher with the
increasing values of both Ra and φ; that plays a vital role for controlling the
specified temperature in the studied domain.
