Selenium (Se) and tellurium (Te) based glasses have unique physical and chemical characteristics that can be manipulated with by the addition of metal alloys. In this study, the thermophysical properties of Se80Te20 and Se80Te10M10 (where M = cadmium (Cd), indium (In), and antimony (Sb)) chalcogenide (containing one or more S, Se, or Te) glasses are investigated to test their use in industrial applications. The transient plane source (TPS) ...
Fiberglass is used inside car mufflers as a noise reducer and insulator. The insulating properties of the fiberglass eliminates the need for muffler heat shields, however to properly design vehicles without heat shields, it is important to know the thermal conductivity of fiberglass at high temperatures. A TPS Thermal Constants Analyzer was used to measure the thermal conductivity of glass fibers with diameters of 17 µm and 24 µm. Each sample was ...
Insulation is a vital component in the construction industry, notably in this study, glass wool. Maximizing the hydrothermal performance of glass wool is key when dealing with water vapor, humidity and permeability. Although insulation does not generally come in contact with liquids, it is important to consider all outcomes, with likelihood of accidents occurring and the varying levels of workmanship. The transient technique was employed to thermally characterize glass wool ...
The effective thermal conductivity and thermal diffusivity was measured for chalcogenide glass samples of the formulation Ge30-xSe70Sbx (x = 10, 15, 20, 25). It was found that both the effective thermal conductivity and thermal diffusivity were independent of temperature up to 160º C. After this point, both properties were found to increase with increasing temperature until they reached a maximum value at a point near the glass transition temperature of the glass. After reaching ...
The thermal conductivities of refractory materials often used in the glass production industry were evaluated experimentally. The transient plane source technique was used for the thermal conductivity testing. Specifically, the single-sided method was used to avoid destroying the refractory materials. The thermal conductivity was measured at various locations and it was discovered that there was a variation in thermal conductivity between the hot and cold faces of the brick....
