Experiments were carried out in a pilot-scale pulverized coal combustor at the Energy and Environmental Research Center (EERC) burning a Powder River Basin (PRB) subbituminous coal. A scanning mobility particle sizer (SMPS) and an electrical low-pressure impactor (ELPI) were used to measure the particle size distributions (PSDs) in the range of 17 nm to 10 microm at the inlet and outlet of the ...

Supervisory Committee Dr. Andrew Rowe (Department of Mechanical Engineering) Supervisor Dr. Peter Wild (Department of Mechanical Engineering Co-Supervisor Dr. Curran Crawford (Department of Mechanical Engineering) Departmental Member Plug-in hybrid electric vehicles (PHEVs) represent a promising future direction for the personal transportation sector in terms of decreasing the reliance on fossi...

– We present a simple model of electrical transport through a metal–molecule– metal nanojunction that includes charging effects as well as aspects of the electronic structure of the molecule. The interplay of a large charging energy and an asymmetry of the metal– molecule coupling can lead to various effects in non–linear electrical transport. In particular, strong negative differential conduct...

DC fast charging (DCFC) and optimal placing of them is a fundamental factor for the popularization of electric vehicles (EVs). This paper proposes an approach to optimize place and size of charging stations based on genetic algorithm (GA). Target of this method is minimizing cost of conversion of gas stations to charging stations. Another considered issue is minimizing EVs losses to find neares...

Rubloff Minta Martin Professor of Engineering, Department of Materials Science and Engineering and the Institute for Systems Research Electrical energy storage solutions with significantly h...

This work presents a methodology to select the inductors and output capacitor for N-branch interleaved buck converter electric vehicle charging applications. Using this analysis, its possible specify passive components so that ripple of current is below certain limit, as defined in IEC 61851-23:2014 standard electrical vehicles charging. Additionally, it presented define critical each inductor ...

Lhasa is a “solar city” with high altitude, located in a cold zone in China. Due to the lack of mineral energy sources and the fragility of its ecological environment, solar heating technology is the first choice to satisfy the demand of indoor thermal comfort for building heating. In this study, an accurate solar heating system in Lhasa was investigated under the simultaneous charging and disc...

Transportation electrification can significantly reduce carbon footprint and accelerate the modernization of aging electric infrastructure. In U.S., growing adoption vehicles (EVs) will impact electrical grid associated greenhouse gas emissions, but with significant differences between balancing regions due to diverse characteristics their grids. This work assesses impacts increasing penetratio...

Compared with the traditional slow charging loads, random integration of large scale fast charging loads will exert more serious impacts on the security of power network operation. Besides, to maximize social benefits, effective scheduling strategy guiding fast charging behaviors should be formulated rather than simply increasing infrastructure construction investments on the power grid. This p...
