The power needs for extended all-electric operation of plug-in hybrid electric vehicles (PHEVs) require much more on-board energy than the lower-density energy typically provided by nickel-metal-hydride batteries. The current engineering solution is to link several parallel strings of lithium-ion battery cells within a battery module and to link several modules into larger battery packs.
When the Deepwater Horizon oil rig exploded off the Louisiana coast in April, it caused the first major deepsea oil spill and became the first spill where chemical dispersants were used far below the water’s surface. Researchers have detected toxic microdroplets spreading in concentrations that may be lethal to wildlife.
David Bromwich, Ph.D., and his research team are leveraging the computing and storage resources of the Ohio Supercomputer Center (OSC) to synthesize historical weather data from a region of nearly 29-million square miles – everything north of Minneapolis, Minn.; Turin, Italy; and the Black Sea. The team is integrating multiple enormous databases containing eleven years of satellite readings and
Slated for launch in 2019-20, the Surface Water and Ocean Topo-graphy (SWOT) satellite mission is a collaborative project of NASA and the French space agency, Centre National d’Etudes Spatiales. SWOT features a swath-mapping radar interferometer that will provide data on inland bodies of water, as well as mapping ocean circulation at high spatial resolution.
Turbomachinery, such as that found in compressors and turbines, is instrumental in today's aeronautic, automotive, marine, space and industrial power generation. To achieve the most efficient propulsion and power systems, engine designers must understand the physics of very complex air-flow fields produced within multiple stages of constantly rotating rotors and stators.
