The researchers in this study presented a functional means of assessing the quality of milk, by measuring fat content, using a thermal constants analyzer. Multiple tests were performed, by altering probe design, probe size and thermal contacting area, to achieve optimal test parameters. The research concluded the possibility of designing a probe capable of measuring the fat content of milk with a less than 0.1% sensitivity. Research also concluded that the ...
As buildings are constructed, pores and cavities are formed within the building envelope and can cause issues with coupled transient radiation-natural convection heat transfer. This research aims to develop a model to minimize the empty space in the area lining the exterior and interior of the building (building envelope). As cavities and pores are present within the building envelope, issues of heat loss and high energy consumptions arise. An improved ...
In this paper silica aerogels were synthesized using solvent exchange and surface modification of wet gels from waterglass using IPA/TMCS/n-Hexane solution. The densities, porosities, and specific surface areas were measured. Three different mixing methods were employed to determine their effect on the thermal and mechanical properties of the aerogel. Thermal conductivity testing revealed thermal conductivity readings ranging from 0.03–0.12 W/m·K....
This research proposed a new, flame retardant, shape-stabilized phase change material (PCM), for use in thermal energy storage. Typical paraffin and high-density polyethylene has great shape retention, however is highly flammable and has a low thermal conductivity. Researchers introduced expanded graphite and an intumescent flame retardant to the mix to improve the thermal properties and flammability, respectively. After several tests, including a thermal conductivity evaluation, on multiple variations of the ...
This experiment outlined an investigation into heat transfer of two water-based nanofluids; H2O-Al2O3 and H2O-Cu. The absorbency and thermal conductivity of both nanofluids was measured under various pH values and sodium dodecylbenzene sulfonate (SDBS) concentrations, to determine whether an effect on heat transfer is present. The results concluded that the stability and thermal conductivity of the nanofluids are greatly dependent on the pH values and SDBS concentrations ...
