Abstract
Nanofluids have budding fluids in the field of heat transfer applications. Hybrid nanofluid is a new emerging class of nanofluids that has nanocomposite dispersed in the base fluid. In this work, synthesis, characterization, and investigation of the heat transfer performance of novel Ag2ZrO3/EG hybrid nanofluid in the field of thermal management have been reported. Silver zirconate (Ag2ZrO3) nanoparticle disseminated in a base fluid (EG) has been used to enhance heat transfer properties in the heat exchanger. The heat transfer performance of the new hybrid Ag2ZrO3/EG nanofluid was studied experimentally at various volume concentrations (0.025, 0.05, 0.075, 0.1, and 0.2%) and temperature range between 35-55oC. Heat transfer coefficient and thermal conductivity enhancement were observed to be 76.37% and 56.2% at 0.2vol. %, which exhibits progressive performance as compared to ZrO2/EG, Al2O3/EG nanofluids. The novel nanofluid shows an excellent replacement potential for advanced fluids used in thermal-based applications.
