EXPERIMENTAL STUDY FOR THERMAL PERFORMANCE AND PRESSURE LOSS CHARACTERISTICS ON A CAR RADIATOR USING NATURE (RICE HUSK) BASED SiO2 NANO-FLUID

Abstract

This research investigates the application of silicon dioxide (SiO₂) nanoparticles synthesized from rice husk to improve the thermal performance of car radiators. The study aims to enhance conventional heat transfer fluids by incorporating these nanoparticles into a base fluid. The paper focuses on the experimental evaluation of rice husk-based SiO2 nanofluids as a novel coolant in automotive cooling systems. Experiments were conducted using a specially designed car radiator setup under conditions that simulate real-world scenarios. Various volume concentrations of SiO₂ nanoparticles (0.07% and 0.1%) were prepared and tested under different operating conditions. The findings demonstrate that the addition of natural SiO₂ nanoparticles significantly enhances the heat transfer efficiency of the car radiator. However, higher concentrations can lead to increased pressure drops, resulting in greater pumping power requirements. This study strongly advocates for their use in the automotive industry to design and develop more efficient and environmentally friendly cooling systems, ultimately improving vehicle energy efficiency.
