This article is a literature review of research that has been done on the thermal conductivity of cast iron. The article outlines the effects of graphite additives, alloying elements, matrix, and temperature on the thermal conductivity. Numerical models that have been developed are also discussed in the review....
A numerical model is developed to describe the thermal conductivity, hydration, and moisture content of Portland cement mortar specimens. In order to develop the model, the thermal conductivity and specific heat of the mortar specimens were measured using the transient plane source method. The model was able to correctly describe the evolution of heat and the degree of hydration in both semi-adiabatic and steam curing conditions....
Low-density microcellular non-isocyanate polyurethane (NIPU) foams were prepared using biological compounds and carbon dioxide. The morphology of these foams was investigated by scanning electron microscopy (SEM), and the thermal conductivity was determined using the transient plane source (TPS) method. It was concluded that a study needed to be undertaken to determine how to fine tune the morphology of the foams in order to decrease the thermal conductivity of the foams....
Nanocomposite phase change materials (PCMs) were prepared by adding silver nanoparticles to isotactic polypropylene (iPP) and an iPP/paraffin wax phase change materials. The Ag nanoparticles were found to be well dispersed in both iPP and the iPP/wax composite, and filler agglomeration was found to increase with increasing filler content. The nanoparticles did not significantly affect the modulus of the iPP on its own, but when Ag and paraffin ...
The work presented in this thesis was performed in order to generate knowledge of heat storage in building structures. The goal was to discover what material could most effectively reduce peak powers required by buildings by keeping buildings warm or cool without the necessity of using power....
