Post-Doc/Recent Staff Seminar (PReSS)

The Good, the Bad and the Ugly: Meditations on Textured Lead-Free Ferroelectrics
Michael R. Winter (2454)
Sandia National Laboratories, Albuquerque
Crystalline texturing of materials presents opportunities to dramatically enhance specific material properties, but may result in some unintended consequences as well. To most effectively leverage the benefits of texture, both the favorable and adverse changes in the material properties must be well understood in the context of the desired application. We will explore some of the ramifications of texturing, drawing from recent work on texturing the bismuth titanium oxide lead-free ferroelectric system. Approaching single crystal orientation, the texture-induced changes in dielectric properties in this system elucidate many of the improvements and drawbacks that anisotropic materials present.
Diesel spray and combustion: how to get better fuel economy
while maintaining clean exhaust gases?
Sanghoon Kook (8362)
Sandia National Laboratories, Livermore, CA
A diesel powered car can get 20 to 30% higher fuel economy than the current gasoline car due to its compression-ignition nature. This high efficiency is already comparable to costly gasoline-electric hybrid vehicles and if a diesel engine is hybridized with an electric motor, much higher efficiency is expected. The hurdles that block massive introduction of diesel cars to U.S. are people’s environmental concern and associated EPA regulations to hazardous exhaust gases such as particulate matter (PM) and nitrogen oxides (NOx).
The first part of this seminar introduces how we have clarified the fundamentals of diesel combustion so that automotive manufactures can comply with the regulations. The influence of ambient gas dilution that can decrease diesel flame temperature to the levels lower than the soot and NOx formation limit will be presented. This is followed by the recent findings in potential sources of in-cylinder unburned hydrocarbon (UHC) and carbon monoxide (CO). The transient diesel spray mixing process, jet-wall interaction and fuel distribution, and optimized in-cylinder flow structure creating an effective mixing plane will be discussed as a way to further improve fuel economy.
