摘要

This paper presents a comprehensive investigation of the convective heat transfer characteristics of nanofluid flow in a channel with a heated obstacle at the bottom, using the Lattice Boltzmann Method (LBM). The study systematically investigates the effects of Reynolds number, nanoparticle volume fraction and obstacle height on the heat transfer efficiency. The experimental setup consists of a rectangular channel with different heated obstacle configurations and a nanofluid consisting of copper nanoparticles dispersed in water to enhance thermal conductivity. Meticulous simulations reveal the significant potential of nanofluids to enhance convective heat transfer, advancing our understanding of fluid dynamics in thermal systems. The research elucidates the intricate relationship between flow dynamics and nanoparticle concentration, providing invaluable insights for optimizing heat transfer processes in various engineering applications. In summary, this study highlights the critical role of nanoparticle properties and flow characteristics in improving the efficiency of thermal systems, providing essential guidance for improving heat transfer methods.
