Natural convection flow and heat transfer in cavities or
enclosures has been extensively studied in past decades
regarding the numerous applications in several industrial
fields. Examples include electronic devices cooling,
lubrication technologies, food processing, float glass
production, flow and heat transfer in solar ponds,
thermal-hydraulics of nuclear reactors and solar collectors.
Natural convection flows are particularly difficult to control
because they depend on various factors such as the geometry,
fluid thermo-physical properties etc. [1-2].
