Highly Thermo-conductive Fluid with Boron Nitride Nanofillers

This study aims to use Boron Nitride (BN) materials as thermo-conductive fillers to enhance the heat transfer in fluids. For this study, BN nanotubes, and nanospheres were added to fluids, to test for individual thermal enhancements. With the addition of BN nanotubes to water, the thermal conductivity of the fluid was enhanced by 2.6 times. Also noted, was the increase in conductivity of the fluid with the addition of BN nanospheres. ...

Thermal conductivity and mechanical properties of BN-filled epoxy composite: effects of filler content, mixing conditions and BN agglomerate size

Boron Nitride filled epoxy composites are explored on a thermal and mechanical scale within this research article. Researchers took special interest in the effect of filler content, mixing conditions and Boron Nitride agglomerate size, on the thermal conductivity of the composite. Experimental results alluded to an increase in thermal conductivity, as filler content, and mixing speed, time and temperature increased. On the other hand, as the Boron Nitride agglomerate size ...

Surfactant-free ionic liquid-based nanofluids with remarkable thermal conductivity enhancement at very low loading of graphene

The Transient Plane Source method was used in this research article to measure the thermal conductivity of an Ionanofluid, highly stable graphene (GE)-based nanofluid, at various temperatures. Researchers took special note of the effects of temperature, GE loading, presence of multi-walled carbon nanotubes (MWCNTs), on the thermal conductivity of the nanofluid. Through experimental testing, it was determined that the nanofluid elicited a higher thermal conductivity, as compared to its ...

Enhanced thermal conductivity by aggregation in heat transfer nanofluids containing metal oxide nanoparticles and carbon nanotubes

The thermal conductivity of heat transfer nanofluids has been determined to increase by 10%, when containing metal oxide nanoparticles and carbon nanotubes. The fluid viscosity of the nanofluids is relatively the same as water, and therefore cannot not account for the increase in thermal conductivity. However, the fashion in which the metal oxide particles conglomerate within the fluid could be a potential explanation for the spike. Results show that under the ...

Properties of F-free glass system as a mold flux: viscosity, thermal conductivity and crystallization behavior

In mold fluxes, fluorine is generally added to reduce viscosity and solidification. The fluorine however, tends to cause corrosion of the casting machine and leads to environmental pollution. To potentially rid this design of these issues, researchers in this study examined the Fluorine-free mold flux, in a specific glass system. Properties such as viscosity, thermal conductivity and crystallization behaviour were all analyzed and compared to the values for the commercial ...
