The present work may deal with the flow, heat transfer and entropy dissections of hydromagnetic buoyancy-driven nanoliquid inside a diamond-shaped container considering ⊥- shaped obstacle of varying configurations subject to heat/sink source and porous matrix. The importance of the above problem is due its potential utilizations in modern industries such as thermal extrusion systems, solar energy collectors, heat exchangers, microelectronic cooling, automobiles, building ventilation, bio-medicine etc. The equations governed may well be solved via finite element method. The present work’s novelty would be the introduction of ⊥- shaped obstacle of varying configurations in a diamond shaped cavity embodying a porous matrix and analyzing the flow along with heat transfer aspects there in. The main findings are that alteration of flow nature from hydrodynamic to hydromagnetic whittles down streamlines and augments isotherms at given Rayleigh number in presence of source/sink subject to porous medium. Total entropy exhibits 3896 % enhancement and average Bejan number shows sharp 85.5 % diminution due to rise of Rayleigh number. The outcomes of the present study finds effective and persistent industrial cooling due to better stability of alumina nanoparticles in nanofluid involved in complex geometries like diamond shaped cavities which is the beyond of existing literature.
