SINOPSIS

Steady natural convective flow and heat transfer in a two-dimensional enclosure with a centrally placed isoflux thin partition utilizing different fluids are investigated for a range of Rayleigh numbers, partition heights, and aspect ratios. The enclosure has two vertical isothermal walls and two horizontal adiabatic walls. The present study is based on a similar configuration with an isoflux thin partition symmetrically embedded at the bottom wall. The governing equations are modeled by a stream function-vorticity formulation and are solved numerically by the finite-difference approach. The Rayleigh number ranges from 103 to 106 . The study includes computations for enclosures at various partition heights ranging from 0.2 to 0.7, aspect ratio from 0.5 to 2, and isoflux values ranging from 0.5 to 2. The fluids used are air, fluorocarbon liquid (FC 77), and ethylene glycol. A comprehensive comparison with previously published numerical and experimental results showed an excellent agreement. The results are presented for different fluids in the form of streamlines and isotherm plots. Variation of the local Nusselt number over the isoflux partition and isothermal wall provides a valuable insight into the physical processes. A numerical correlation is proposed for the heat and fluid flow studies in a wide range of thermal and geometric parameters.
