Thermo-Hydraulic Performance Enhancement of Hybrid Nanofluid-Based Heat Transfer Systems in Industrial Applications

Abstract

The growing demand for efficient thermal management systems in industrial applications has increased the need for advanced heat transfer technologies capable of improving energy efficiency and operational performance. Conventional heat transfer fluids often exhibit limited thermal conductivity and reduced heat dissipation capability under high-temperature operating conditions, restricting their effectiveness in modern industrial systems. This research presents a thermo-hydraulic performance enhancement study of hybrid nanofluid-based heat transfer systems for industrial applications to improve thermal efficiency, heat transfer rate, and fluid flow characteristics. The proposed study investigates the integration of hybrid nanofluids containing multiple nanoparticles dispersed within conventional base fluids to enhance thermal conductivity and convective heat transfer performance. Experimental and numerical analyses are conducted to evaluate the influence of nanoparticle concentration, flow rate, temperature variation, particle size, and Reynolds number on the thermo-hydraulic behavior of the heat transfer system. The study further examines pressure drop characteristics, friction factor behavior, pumping power requirements, and thermal stability under varying operational conditions. Computational fluid dynamics and heat transfer modeling techniques are employed to simulate fluid flow and temperature distribution within industrial heat exchanger configurations. Performance evaluation is carried out using parameters such as Nusselt number, thermal conductivity enhancement, heat transfer coefficient, pressure drop, pumping power, and overall system efficiency. Experimental results demonstrate that hybrid nanofluids significantly improve thermal performance and heat dissipation capability compared with conventional heat transfer fluids.
