Thermal conductivity of nanofluids prepared from biobased nanomaterials dispersed in 60:40 ethylene glycol/water base fluid

Abstract

In the present study, experimental investigation on thermal conductivity of green nanofluids prepared from coconut fibre-based nanoparticles and suspended in 60:40 ethylene glycol (EG) water (W) mixture was carried out. The measurement of thermal conductivity was conducted at 15 °C to 60 °C at mass fractions of 0.04 wt%, 0.08 wt%, 0.5 wt% and 1 wt%. The results show deterioration in thermal conductivity with an increasing temperature. Also the deterioration increased as the mass fraction increased.
