Experimental study on the thermal conductivity of graphene-carbon nanotube-silver nanoparticle ternary hybrid nanofluids.

ABSTRACT: In this study, high-thermal-conductivity ternary hybrid nanofluids incorporating graphene-carbon nanotube-silver (Gr-CNT-AgNP) hybrid materials were successfully prepared. The influence of nanoparticle concentration (0-0.05 vol%) and operating temperature (30-55 °C) on the thermal conductivity of both water-based and ethylene-glycol (EG)-based nanofluids was systematically examined. The thermal conductivity increased monotonically with Gr-CNT-AgNP loading, achieving maximum enhancements of 38% for water-based and 52% for EG-based nanofluids at 0.05 vol% and 55 °C. Quantitative analysis showed that concentration contributed more strongly to conductivity improvement than temperature, though temperature-induced intensification of Brownian motion provided an additional enhancement of up to ∼10
