Hybrid Energy Harvesting, Nazanin R. Ghavamabadi

Graduate Research Posters

Between 20% to 50% of industrial energy input is lost as waste heat in the form of hot exhaust gases, cooling water and energy loss from generating equipment. Vibrations and variable heating are a common form of waste energy in motors, generators, power cables exposed to ambient temperatures, fuel exhausts from vehicles, and various types of heavy machinery. The recovery of even a fraction of this lost energy would have a transformational impact on the utility industry since the demand for energy is increasing and the impact of this demand on the environment is significant. Recent technical breakthroughs in new …

Electrospinning is a widely applicable technique that generates non-woven fibers in the micro and nano range. In this project two of its applications are highlighted namely filtration media and enhancement of wettability. The first project demonstrates that electrospinning can be used to produce new fiber filtration media with controlled microstructure. The bimodal and unimodal orthogonal and random filters were made and characterized against their filtration efficiency and pressure drop. Figure of Merit (FOM) was also calculated and discussed. It is shown that the FOM increases when the electrospun fibers are arranged into alternating layers of aligned course and fine fibers. …
