The current study examines the behavior of a transformer-oil-based tri-hybrid nanostructured material flow between revolving, double-stretchable disks, considering the effects of activation/dissipative energy. A better understanding of these effects helps us in the improvement of thermal management systems, efficiencies of mechanical systems, and to gain the high-performance of electrical systems. Spherical and non-spherical shapes of nanoparticles Fe 3 O 4 , TiO 2 , and Cu are studied. The significance of thermal radiation, Lorentz force, and thermal source/sink is also incorporated to make the mathematical model more versatile. Through similarity transformation, the leading equations are transmuted into a highly non-linear and non-dimensional differential system. The obtained differential system depends on the physical boundary conditions and is then simulated using the bvp4c MATLAB solver. The results reveal that flow and heat/mass transport in the tri-hybrid nanostructure material are strongly influenced by revolving, magnetic, Reynolds, and thermochemical parameters. Revolving system suppresses axial motion while enhancing tangential velocity, whereas higher Reynolds numbers enhance heat/mass transport despite reducing thermal/solutal fields. The lower disk exhibits stronger transport rates, and tri-hybrid nanostructured material outperforms hybrid and simple nanostructured materials, with blade-shaped nanoparticles providing superior heat-transport performance.
