The main objective of this research project was to create a material with a very low thermal conductivity at high temperatures, for the conservation of energy in high temperature systems. To accomplish this goal, the researchers incorporated carbon nanofibers into the mesoporous network of monolithic aerogels, with up to a 20 wt.% through an accelerated-gelation sol-gel process. The synthesis process also involved the use of supercritical drying of the aerogels to ...
A new composite zeolite/foam aluminum material is synthesized and its suitability for use in an adsorptive refrigeration system is studied. Current automobile air conditioning systems use vapor compression refrigeration systems which have environmentally unfriendly chemicals and use a significant portion of the engine power of the vehicle. The newly proposed composite zeolite/foam aluminum would work by using the engines heat in order to run the air conditioning systems, ...
The thermal properties of a series of treated and untreated oil palm fiber-reinforced composites were tested at room temperature and atmospheric pressure using the TPS method. Treatment of the composites with varying methods resulted in increases in thermal conductivity, porosity and pore sizes depending on the treatment method used. The dependence of thermal conductivity on temperature was also studied and it was found that the maximum thermal conductivity was at ...
Through the use of experimental (one-sided TPS technique) and theoretical (MD simulations) methods, the thermal conductivity and thermal diffusivity of methane hydrate was studied. Varying concentrations of methane hydrate were studied. The effect of pressure on the thermal properties of methane hydrate was also studied and didn't have a significant effect on the measurement of thermal conductivity. The results obtained from the experimental and theoretical methods agreed well with each ...
Through the use of the transient plane source method the researchers were able to measure the thermal conductivity of a collection of cellular metals as well as the in- homogeneities of the samples. The volume of the samples was varied and the density of these individual volumes was calculated from tomography....
