The work attempts to address excessive heating and related risks in most of the engineering systems. Perforations are well known to boost heat transfer. Present work is an attempt to pact optimization of perforated enclosures for internal natural convection heat transfer. Heat dissipation effect is experimented over a flat plate and implications are understood with variation in convective heat transfer coefficient. Controlling parameters viz., plate orientation, perforation shape and size, enclosures in diverse configurations are varied systematically aiming enhanced heat transfer. Results confirm fact that perforated enclosures significantly affect the heat transportation. Enclosures with varying perforations are found to yield distinct heat sink characteristics. For varying perforation shape, size and plate orientation, the heat transfer rate variation is owed by the resultant flow behavior which governs the energy transference. The complied results are noted as excellent physical insight and optimized to propose a novel design for operations under varying heat transfer requirements for wide-ranging applications.
