The thermal conductivities of paraffin-based composite phase change materials (PCMs) containing different types of graphene nanoparticles were determined using the transient plane source method. It was determined that the thermal conductivity was increased by the addition of the nanoparticles, and the enhancement was greater for ...
Four different paraffin-based nanocomposite phase change materials (PCMs) were prepared by dispersion of 20 v. % of graphene, multi-walled carbon nanotubes (MWCNTs), aluminum, or TiO2 nanoparticles into a paraffin matrix. It was found that the two carbon-based nanoparticles reduced the time required for melting and solidification of ...
The thermal conductivities of four composite paraffin phase change materials (PCMs) containing embedded multi-walled carbon nanotubes (MWCNTs) with varying dimensions were determined. The goals of this study were to investigate the interfacial thermal resistance between two MWCNTs, and to investigate the ballistic and diffusive components ...
The authors outline a method of enhancing the thermal properties of a paraffin phase change material through the addition of herringbone-style graphite nanofibers (HGNFs). It was found that the solid-phase thermal conductivity increased exponentially with the presence of HGNFs; however, a significant increase in the ...
The authors state that the TPS technique isn't an accurate method for the measurement of thermal conductivity, thermal diffusivity and volumetric heat capacity of liquids. This is due to the effects of natural convection caused by the sensor which introduce a significant error in the ...
