A case study on enhanced thermal transport of radiated hybrid ferro-nanofluid (Fe3O4/CoFe2O4-NiZnFe2O4/MnZnFe2O4) with finite speed thermal propagation

The ferromagnetic hybrid nanomaterials offer exceptional thermal performances, magnetic controllability and flow controllability, make these materials promising candidates for the next-generation thermal systems. This investigation presents thermal applications of radiated ferro-nanofluid comprising the suspension of ferrite-cobalt ferrite (Fe 3 O 4 /CoFe 2 O 4 ) along with nickel zinc ferrite-manganese zinc ferrite (NiZnFe 2 O 4 /MnZnFe 2 O 4 ) nanoparticles. Thermal model incorporates the nonlinear radiated effects and chemical reactive application. In order to capture the finite-speed thermal and mass propagation, a famous Cattaneo–Christov model has been implemented. The source of flow is the porous stretching surface. Shooting numerical procedure is adopted for simulating the governing expressions. Physical visualization of problem is presented via parametric approach . The claimed findings reveal that the developed hybrid ferro-nanofluid model be utilized in design of modern thermal systems including including solar collectors, nuclear systems, electronics cooling, bio-thermal control devices and magnetically controlled microfluidic devices.
