Observations demonstrated that an increase in concentration enhances heat transfer performance, with Nusselt numbers ranging 112.0 at 2.0% concentration results, considering that the influence of mass flow rate on the heat dissipation coefficient rose sharply and heat transfer coefficient reached the maximum of 270.8 W/m<sup>2</sup>·K.

This work optimizes Al₂O₃ nanofluids in multilayer MCHS, boosting heat transfer to 270.8 W/m<sup>2</sup>·K while controlling pressure drop. The optimal 1.5% concentration at 0.04 kg/s offers efficient, scalable cooling solutions for electronics, automotive, and industrial applications. This research also utilized a multi-objective optimization strategy that determined proper operating conditions that would result in both thermal efficiency and pumping power.
