The Experimental Analysis of the Thermal Performance of a Shell and Tube Heat Exchanger Using a Nanocomposite Fluid

Abstract

Nanofluid is a multiple phase solid liquid fluid that shows promise as a heat transfer fluid. Adding mono nanoparticles to a base fluid to increase heat transmission is a proven approach. Currently, researchers are concentrating on impregnating two or more nanoparticles in hybrid or composite form into base fluids called hybrid or nano composite fluid to increase heat transfer properties. The current work creates a novel nanocomposite particle (TiO₂-Ag). The produced nanocomposite particle is characterized using conventional procedures. High Resolution Transmission Electron Microscope (HRTEM) study confirms that silver (Ag) nanoparticles are bonded to the surface of titanium dioxide (TiO₂). The XRD peak and EDAX confirm the development of TiO₂–Ag nanocomposite particle concentration of silver (Ag) around 9.5 wt.% and titania (TiO₂) 90.5 wt.%.
