摘要

Hybrid nanofluids are advanced heat transfer fluids compared to base fluids and mono nanofluids due to the combination of different nanoparticles, which exhibit enhanced thermal properties. Their outstanding thermal efficiency makes them crucial for various industrial and technological uses. This study investigates the effect of temperature-dependent fluid properties on the flow and thermal characteristics of hybrid nanofluids over an exponentially stretched sheet. The present work considers variations in viscosity, thermal conductivity, and mass diffusivity. The model also accounts for Joule heating, viscous dissipation, activation energy, and thermal and concentration slip effects. Based on these effects, the formulated governing partial differential equations of the flow are transformed into ordinary differential equations using similarity variables and subsequently solved using the bvp4c solver in MATLAB. The impacts of various key factors on flow distributions and engineering quantities are examined and presented using graphs and tables for viscous, mono, and hybrid nanofluids. The findings indicate that hybrid nanofluids markedly improve heat transfer efficiency by 7.13% in comparison with viscous and mono nanofluids, with differing viscosity and thermal conductivity being instrumental in altering boundary layer characteristics. The velocity profile decreases with increasing magnetic field strength, whereas the skin friction increases by up to 6.73% for hybrid nanofluids. An increase in the activation energy factor leads to a rise in the hybrid nanofluid concentration distribution, while reducing mass transfer by 20.47%.
