Abstract

In the current work, the heat transport characteristics of ethylene glycol with different volume fractions of silver nanoparticles dispersed to form a nanofluid that flows through an inner tube of the annular heat exchanger were investigated experimentally. The mass flow rate of nanofluid varied from 5 g/s to 25 g/s at 50°C inlet temperature of nanofluid on the heat transfer co-efficient were carried out under laminar flow conditions. The nanofluid was prepared with 0.05% and 0.1% volume percent of silver nanoparticles. The thermo-physical characteristics of pure ethylene glycol and silver/ethylene glycol nanofluid were measured experimentally. The heat transfer co-efficient was significantly increased with respect to Reynolds number and volume percent of silver nanoparticles. The experimental results show that the of convective heat transfer coefficient of the nanofluids increases up to 38% at a volume percent of 0.1% with those compared with basefluid at same Reynolds number. The enhanced thermal conductivity of nanofluid and the clustering of nanoparticles could be the probable reasons for the increment of heat transfer co-efficient. The pressure drop of the nanofluid increases as a function of Reynolds number and volume percent of nanoparticles. The increment in pressure drop is more predominant with respect to Reynolds number as compared to volume percent of nanoparticles.
