An experimental determination of temperature-dependent thermal conductivity of cyclohexane-based nanofluids

Many studies have been conducted on nanofluids with bases of water and ethylene glycol. Cyclic alkane, more commonly known as cyclohexane, can be used as the base liquid for cold storage, however minimal research has been conducted with these solutions. This study explores the temperature-dependent thermal conductivity of cyclohexane with copper oxide nanoparticles. Thermal conductivity was measured using the Thermal Constants Analyser. Samples were tested between 10 °C and 50 °C, increasing ...

Enhanced Thermal Conductivity and Expedited Freezing of Nanoparticle Suspensions Utilized as Novel Phase Change Materials

Nanoparticle suspensions were prepared in two PCMs to determine the effect of the addition of nanoparticles on thermal conductivity and expediting freezing. The base PCMs used were cyclohexane and eicosane, and copper oxide nanoparticles were suspended in these hydrocarbons to produce nano-enhanced PCMs (nePCMs). The enhancement of thermal conductivity and expedited freezing were investigated by analytic, experimental, and numerical methods. The thermal conductivity in the liquid phase was significantly enhanced ...

Thermal conductivity enhancement of nanostructure-based colloidal suspensions utilized as phase change materials for thermal energy storage: A review

The authors have presented a literature review on computational and experimental studies on the thermal conductivity of nanostructure enhanced phase change materials (nePCMs). It was found that a wide range of nanostructures have been investigated, from carbon nanostructures and carbon nanotubes to metal and metal oxide nanoparticles. The carbon nanostructures and nanotubes were found to generally enhance the thermal conductivity of the PCMs by a greater amount than metal or ...

Temperature-dependent thermal conductivity of eicosane-based phase change materials with copper oxide nanoparticles

In this study, pure eicosane and eicosane-CuO solid composites were prepared using ambient and ice-water bath solidification methods. A Thermal Constants Analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) technique. Results showed that for both solidification methods, composite thermal conductivity was independent of temperature up to a point, and the composites with the highest nanoparticle concentrations had the highest thermal conductivity. Although the composites ...

An experimental investigation of enhanced thermal conductivity and expedited unidirectional freezing of cyclohexane-based nanoparticle suspensions utilized as nano-enhanced phase change materials (NePCM)

Through the addition of copper oxide nanoparticles to cyclohexane in varying concentrations, a series of nano-enhanced phase change materials (NePCM) were prepared. The transient plane source (TPS) technique was used to characterize the NePCM at multiple temperatures. It was determined experimentally that increasing concentrations of nanoparticles in the liquid phase resulted in increasing thermal conductivity, but increasing nanoparticle concentration in the solid phase didn't have the same effect.Unidirectional freezing ...
