This article is a review of techniques used to measure thermal transport properties. Emphasis is placed on the hot strip and pulse hot strip methods. The development, and theory of each method is described in detail....
The authors have carried out an experimental and numerical study on the effects of seeding Al2O3 nanoparticles in a paraffin wax phase change material (PCM) on the thermal conductivity and the latent heat of fusion. It was determined that the addition of the nanoparticles (up to 1 wt. %) resulted in the nano-PCM having a higher thermal conductivity than the pure paraffin wax. The latent heat of fusion was also found ...
The effects of using different fillers and the effects of filler content and particle size on the thermal properties of thermal interface materials were investigated. The most prominent enhancement in thermal conductivity was observed for samples containing carbon nanotubes and graphite. The filler particle size was also found to significantly affect the thermal conductivity, as smaller fillers resulted in a higher thermal conductivity. The article also describes two sample holders ...
The thermal conductivity and thermal diffusivity of rare earth oxide powders were measured using the transient plane source technique. Specifically, powders of gadolinium oxide, samarium oxide, and yttrium oxide were measured. A previously developed theoretical model was used to predict the effective thermal conductivity and thermal diffusivity of these powders. The experimental results were then compared to values calculated by the theoretical model....
The thermal and mechanical properties of concrete in which normal weight aggregate has been substituted with lightweight aggregates were investigated. The properties were found to be dependent on the volume fraction of the lightweight aggregate, as well as on the nature and quality of the aggregate. The addition of lightweight aggregates resulted in a decreased thermal conductivity, as well as a decreased thermal diffusivity in all samples. The compressive strength ...
