This article studied the thermal conductivity of deionized (DI) water and ethylene glycol (EG) based nanofluids with varying temperatures for different volume fractions of N-(rGO-MWNTs) (nitrogen doped hybrid structure of reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWNTs)). The thermal conductivity was found by using the transient plane source (TPS) method by using a Thermal Analyser. From the experimental results, it was noted that the thermal conductivity of ...
Water is being used to absorb incident light for use in solar power applications. Adding nanoparticles to water improves the solar collection efficiency. In this paper, a Thermal Analyzer measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluids increased with temperature and nanoparticle concentration....
Carbon nanotubes (CNTs) have extremely high thermal conductivity and can raise the thermal conductivity of a polymer matrix when used as an additive. Previous research has shown that random CNT orientation in polymer matrices gives a much lower thermal conductivity value than a specific alignment direction. This project tested the thermal conductivity of oils and polymers. Results were encouraging, with the thermal conductivity of the composites increasing linearly with the ...
In this paper, researchers investigated the effects of multi-walled carbon nanotubes (MWNTs), on the thermal conductivity and phase change enthalpy of palmitic acid (PA), a solid to liquid phase change material. The research concluded that as the concentration of MWNTs is increased, the thermal conductivity of the composite increases, compared to that of PA alone. Also in this study, researchers investigated the effects of various MWNTs surface modifications, on the ...
Thermal conductivity measurements of the same samples were carried out using the TPS method. Thermal testing on carbon nanotubes to study for promising fillers. Thermal conductivity of single-walled carbon nanotubes should enable a further reduction in the filler content required for a given enhancement in the composite properties. For the multi-walled carbon nanotube thermal conductivity increased modestly using this method whereas for the single-walled carbon nanotubes the thermal conductivity was ...
