Numerical analysis of 3D rotational flow of MoS ₂ -Ag/paraffin nanofluid under solar thermal radiation effects

This study investigates the thermal behavior of silver (Ag) and molybdenum dioxide (MoS 2 ) nanofluids in a three-dimensional, rotational flow framework, with paraffin (Pfin) as the base fluid. A key novelty of this research lies in the comparative analysis of MoS 2 -Pfin and Ag-Pfin nanofluids under boundary slippage and convective conditions. Additionally, a hybrid Ag-MoS 2 nanocomposite is introduced to enhance heat transfer characteristics. The mathematical model is solved using an order reduction-based numerical algorithm, providing approximate solutions through an iterative approach. The results, presented in graphical and tabular formats, offer quantitative insights into the impact of primary parameters on heat transport. The findings reveal that the incorporation of Ag-MoS 2 nanoparticles significantly improves heat transfer rates. Furthermore, the thermal boundary layer thickness increases with the microrotation parameter in both nanofluid cases. A critical evaluation of the results demonstrates that MoS 2 exhibits superior heat transfer properties compared to Ag, highlighting its potential for advanced thermal management applications.
