Study of heat transfer characteristics of Sio2 nanoparticles in heat pipes

Abstract

This project deal with study of heat transfer characteristics of silicon oxide, SiO2 in heat pipe. To achieve better performance of heat pipe, increasing its efficiency is a challenge nowadays. Effects of implementation of nanoparticles on efficiency of heat pipe have been studied in this project. Concept of heat transfer applied in order to analyse characteristics of nanofluid. The main objective of this project was to study the effect of nanoparticles on the performance of thermosyphon by focusing on its specific heat capacity. For this project, a test rig was fabricated and nanofluids were prepared using SiO2 nanoparticle and water. Steps and processes on test rig fabrication have been explained clearly. After conducting the experiment, the results were analysed and briefly discussed. It is observed that as concentration of nanofluid increases, specific heat capacity were decreased and lead to rise in efficiency. Thermal performance of thermosyphon with nanofluid had better heat enhancement compared to water and this resulted in low power consumption.
