Improving thermal efficiency through Cu-MoS2 hybrid nanomaterials: A numerical and statistical approach

Abstract

Hybrid nanofluids exhibit enhanced thermal and transport properties due to synergistic interactions between their constituent materials. In this study, we present a novel investigation into the flow characteristics of a hybrid nanofluid surrounding a stretching cylinder. Our approach involves integrating molybdenum disulfide and copper nanoparticles into a water-based fluid. It considers stretching along the z-axis and delves into heat transfer and statistical aspects while accounting for thermal radiation and Joule heating effects and assuming negligible dissipation effects. Moreover, the hybrid nanofluid permeates a positioned porous medium above the cylinder. The article contributes to a deeper understanding of mixed nanofluid behavior and heat transfer within intricate conditions, ultimately aiding in the optimization and design of diverse engineering and industrial processes. Observations display a substantial decrease in energy and flow field attributes as a result of thermal and velocity slip effects. Also, the thermal radiation augments the energy transport and Nusselt number significantly.
