Heat and mass transfer impact on Casson nanofluid flow across a stretching surface along with activation energy

Hybrid nanofluids, with their advanced thermophysical properties and promising role in boosting heat transfer efficiency, have become a key area of focus for many researchers in the current era of technology. Novelty of this paper is mainly involved with heat transmission in variable thickness geometry in the existence of an inclined magnetic field, activation energy, and non-linear thermal radiation. Hybrid nanofluid composites are made by dissolving Al2O3(Aluminium oxide) and TiO2(Titanium oxide) In base fluid, engine oil. The modified governing equations for momentum and temperature, under relevant boundary conditions, are solved numerically using the precise and efficient bvp-4c Method. The Consequences of an inclined magnetic field, non-linear thermal radiation, power index of velocity, and activation energy are analysed thoroughly, and the outcomes are plotted graphically. Based on the results, we can observe that the fluid velocity decreases as a results considering a magnetic field that is inclined. As the power index velocity rises, the velocity profile reveals a decline.
