摘要：

Experiments were carried out on the measurement of viscosity and thermal conductivity of multi-walled carbon nanotubes (MWCNT)-water nanofluids prepared using gum arabic as dispersant. The influence of temperature (28-60 degrees C), MWCNT concentration (0.14-0.24 vol%) on viscosity and effective thermal conductivity has been investigated. Our results on the effect of MWCNT concentration on relative viscosity and thermal conductivity ratio are in qualitative agreement with those reported in literature. Thermal conductivity ratios increase strongly with temperature, especially above 45 degrees C. Relative viscosities too increased with temperature above 45 degrees C at relatively higher MWCNT concentration indicating the potential role of Brownian motion.
