Heat transfer enhancement has become a critical area of research due to increasing demand for efficient thermal management in engineering applications such as electronic cooling, automotive systems, power plants, and renewable energy devices. Conventional heat transfer fluids such as water, ethylene glycol, and oils exhibit limited thermal conductivity, restricting system performance. Nanofluids, engineered by dispersing nanoparticles into base fluids, have emerged as a promising solution to overcome these limitations. This study presents a mathematical modeling and analytical investigation of heat transfer characteristics in nanofluid-based cooling systems. The research analyzes the effects of nanoparticle volume fraction, Reynolds number, and temperature gradient on heat transfer enhancement and flow behavior. Governing equations for fluid flow and heat transfer are developed and solved analytically. The findings demonstrate that nanofluids significantly enhance convective heat transfer performance compared to conventional fluids, making them suitable for advanced thermal management applications.
