Agro-composite materials were produced from flax shaves and the properties of these composites were determined experimentally. The structure and morphology of the composites was determined by scanning electron microscopy (SEM), and their thermal conductivities were determined using the transient plane source method. These properties, as well as mechanical, hydric, and acoustic properties were determined as a function of the structure and size of the flax shaves....
The ability of Cu-H2O nanofluids to perform as phase change materials (PCMs) is investigated. The supercooling behavior of the nanofluids was determined as a function of copper nanoparticle concentration. The contact angle and thermal conductivity of this PCM were also determined experimentally. Based on the experimental results, the authors conclude that these nanofluids could be useful in thermal energy storage applications....
Numerical models for the calculation of thermal conductivity and rheology behavior of alumina and multi-walled carbon nanotube (MWCNT) nanofluids were evaluated by determining these properties experimentally and comparing the results to the models. The thermal conductivity was measured by the transient plane source method, and the dynamic viscosity was determined using a rotational rheometer. A new model was then developed for these nanofluids, including the effects of interfacial thermal resistance. ...
The effects of the addition of three different fillers to a polymer matrix on the thermo-physical properties of the resulting composites were investigated by the authors. Boron nitride, synthetic diamond, and silicon nitride were used as the fillers (up to 2 vol. %), and it was found that their addition did increase the thermal conductivity relative to that of the pure epoxy matrix. Furthermore, it was determined that the thermal conductivities of ...
This article is a review of the methods for measuring thermal conductivity including both steady state and transient methods. The article describes the experimental setup for each method, and it gives a brief description of the theory of each method. A review of models that have been developed for the prediction of thermal conductivity of polymeric nanocomposites is also presented....
