**7. Conclusions**

The boundary layer flow of nanofluids of Al2O3 and *γ*-Al2O3 with various base fluids is carried out on a stretching sheet. We have been successful in developing a numerical solution for the steady BL flow and heat transfer at the stagnation point of nanofluids with a slip boundary condition. The velocity of the sheet's stretching in its own plane *uw*, is different from the velocity of the external flow *U*∞. The similarity ordinary differential equations that were produced are solved using the shooting method in conjunction with the *RK* − 4 approach. For *γ*-Al2O3 nanofluids, we use models of viscosity and thermal conductivity that are built from actual experiments. For Al2O3, the viscosity model from Brinkman and the thermal conductivity model from Maxwell, are used along thermal radiation. The following are some particular findings that has be drawn from this investigation.


ever, *γ*-Al2O3 nanoparticles exhibit the opposite tendency. The Nusselt number of ethylene glycol-based nanofluids is greater than that of water-based nanofluids. The Nusselt number for *γ*-Al2O3 nanoparticles is greater than that of other nanoparticles.
