Owing to the innovating thermal applications of ferromagnetic hybrid nanomaterials thermal engineering and medical sciences, scientists have studied different aspects of hybrid nanofluids. The ferromagnetic hybrid nanomaterials are the most fascinating nanoparticles which convey special applications in the medial sciences like hyperthermia treatment. The ferromagnetic nanomaterials have ability to diagnose the tumor site and destroy the cancer cells heated with magnetic force. The objective of current investigation is to examine the thermal properties of ferromagnetic hybrid nanofluid with assessment of different shape features. The hybrid nanofluid is based on suspension of magnetite cobalt ferrite (CoFe2O4) and iron oxide nanoparticles (Fe3O4) nanoparticles with methanol (CH3OH) base material. The motivations for utilizing Fe3O4 and CoFe2O4 nanoparticles are associated to peak thermal efficiencies. The representation of base fluid properties is justified by using the Casson fluid mode. The source of flow is an isothermal sphere which include applications in the aerospace and bioengineering engineering. The inertial effects are studied with amplification of Darcy Forchheimer model. The applications of four distinct shape features (platelets, bricks, cylinders, blades) associated to (CoFe2O4−Fe3O4)/CH3OH hybrid model have been exclusively studied. The mathematical model is developed by utilizing the famous Tiwari and Das model. The numerical simulations are subject to implementation of Keller Box number scheme. Thermal behavior of hybrid nanofluid model is presented against variation of different flow parameters. It has been observed that change in Darcy number and Forchheimer parameter leads to enhancement of heat transfer. The skin friction coefficient increases for sold volume fraction of magnetite cobalt ferrite and iron oxide nanoparticles. The magnitude of Nusselt number is smaller for bricks shape nanoparticles. Current results present applications in the targeted drug delivery, aerospace cooling systems, heat exchangers, solar thermal systems, bio-heat transfer etc.
