Dissipative MHD flow of ternary hybrid Ag–TiO₂–Al₂O₃/H₂O nanofluid over an inclined sheet with activation energy

This study has been carried out to understand unsteady MHD slip flow of water-based ternary hybrid nanofluid, including platelet Ag, titanium dioxide [Formula: see text] and cylindrical [Formula: see text] nanoparticles, across an angled sheet. The complicated scenario above investigates how ternary hybrid nanofluid behaves when it stretched across an inclined surface in the existence of magnetic field. Understanding of this relationship is essential in complex thermal systems, such as energy-generating technologies and cooling mechanisms. This study can help optimise heat transfer rates, improve thermal conductivity and increase efficiency in real applications by adjusting flow parameters and temperature distribution. In the existence of first-order velocity slip, heat transfer has been examined, taking into account porous media, activation energy, and chemical reaction. The novel impacts of magnetic field and effective thermophysical properties of ternary nanofluid are considered, and a new model for heat transfer is successfully implemented. Oil extraction from hydrocarbon sources and smelting metal and semiconductor combinations to create semiconductor devices comprise two useful applications for this activity. The study is more accommodating due to the Soret effect. The relevant similarity transformations are applied in primary equations, and a built-in bvp4c program is employed for solutions. The effectiveness of the numerical approach is demonstrated by thorough agreement with results published in the past. Key conclusions are as follows: greater values of first-order slip parameter cause the flow to slow down; increase in the Soret number causes the flow to speed up; and fluid movement slips by higher values of the chemical reaction. Activation energy enhances the fluid concentration.
