Consolidated water sorbents with varying densities were prepared by adding expanded graphite treated with sulphuric acid to activated carbon-lithium chloride composites for use as a lab-scale prototype for thermal energy storage. The sorption reactor prototype that was designed was unable to reach the 1 kWh heat storage target. Further research will be done with the goal of developing a 15 kWh reactor which would be capable of meeting the heating demand of ...
Autoclaved aerated concrete was studied because it has potential to be used in the design of energy-efficient buildings. Three different samples were tested, each with a unique density. Of particular interest to this work was the thermal conductivity of the samples, as this material would be used as a thermally insulating concrete. The thermal conductivities were measured at various percentages of moisture content, and it was found that increasing moisture ...
Three techniques were compared for the determination of thermal conductivity in poly-alpha-olefin (PAO)-based nanofluids. The three methods that were used were the transient hot wire, transient plane source, and laser flash techniques. The effects of temperature, nanoparticle concentration, and shape on the thermal conductivity were also examined, and these effects were compared to those predicted by a previously determined model. It was found that the transient hot wire technique ...
The authors have performed a study to determine if heat pulse wax monitoring is capable of measuring the wax thickness build-up in an oil pipeline. A numerical model was developed to simulate the heat pulse equipment and to predict the wax thickness based on the experimental results....
The authors present a method of preparing an aluminum shoe mold by a novel process called vacuum sealed casting. It was determined that the prototype shoe should be made of a resin, and then the mold should be made of aluminum. A composite resin was chosen such that the thermal conductivity, dimension accuracy, and wear resistance were greater than those of the pristine resin. The use of the aluminum mold ...
