Nanofluids garner significant scientific interest due to their exceptional heat-conducting abilities and potential enhance heat transfer efficiency. This manuscript investigates the behavior of a two-dimensional fractional Carreau fluid model on stretched sheet over time, incorporating convection, magnetic fields, nanoparticles, diffusion, thermal radiations. The elucidates viscoelastic nanofluids' memory inheritance properties, employing non-integer Caputo derivatives innovatively. Fundamental equations are transformed into dimensionless form solved using an explicit finite difference approach. Essential parameters like Skin friction coefficient, Nusselt number, Sherwood number accurately determined. Rigorous stability convergence criteria ensure effective solution convergence. Visual representations demonstrate impact each parameter flow. It is noted that temperature gradient increases 49.38% with increase exponent α while it decreases 13.39% M.
