Volume fraction and temperature variations of the effective thermal conductivity of nanodiamond fluids in deionized water

Thermal conductivity enhancements of nanodiamond particles (NDs) suspended in pure deionized (DI) with different volume fractions in the range from 0.8% to 3% have been measured. The highest observed enhancement in the thermal conductivity is 7.2% for a volume fraction of 3% at a temperature of 30 d...

Description
Summary:Thermal conductivity enhancements of nanodiamond particles (NDs) suspended in pure deionized (DI) with different volume fractions in the range from 0.8% to 3% have been measured. The highest observed enhancement in the thermal conductivity is 7.2% for a volume fraction of 3% at a temperature of 30 degree C. The thermal conductivity increases by about 9.8% as the temperature rises to 50 degree C. The new Murshed model (Murshed et al. (2009) [31]) was used to describe the heat transfer enhancement in the ND fluid. While the predicted results overestimate the experimental data, they are in agreement within the experimental errors.
