New Polarized-Depolarized Measurement Capability Extends Use of Raman/Rayleigh Methods to More Flame Types

Allowing single-shot measurements of all major species in nonsooting flames of simple fuels, such as H2 and CH4, spontaneous Raman scattering has been a key Combustion Research Facility (CRF) laser diagnostic technique for fundamental turbulent-combustion studies. However, laser-induced fluorescence from soot precursors tends to interfere significantly with Raman scattering signals—limiting this method’s utility. Such fluorescence […]

New Conceptual Insights into Diesel Engine Fuel-Injection Processes

By combining advanced theory and high-fidelity large eddy simulation, Combustion Research Facility (CRF) researchers Rainer Dahms and Joe Oefelein (both in 8351) have provided new conceptual insights that promise to improve the understanding and prediction of fuel-injection processes in high-pressure diesel engine conditions. Their results, which experiments performed by CRF researchers Lyle Pickett and Julien […]

Two CRF Papers Named “Distinguished” for 34th International Symposium on Combustion

Two papers by CRF researchers have been named distinguished papers for the 34th International Symposium on Combustion held from July 29–August 3, 2012, in Warsaw, Poland. “Synchrotron photoionization measurements of fundamental autoignition reactions: Product formation in low-temperature isobutane oxidation” by Arkke Eskola, Oliver Welz, John Savee, David Osborn, and Craig Taatjes (all in Sandia’s Combustion […]

Northrop-Grumman, GE Partnerships Tap a Wide Range of Sandia Labs Experience

Sandia has signed a pair of umbrella cooperative research and development agreements (CRADAs) with Northrop Grumman Information Systems and General Electric Global Research that will broadly add to the Labs’ research. “These strategic agreements envision long-term partner­ships,” said Brooke Garcia, a Sandia business development specialist who helped negotiate the CRADAs. The Northrop-Grumman CRADA includes research […]

Vehicle Technologies

On November 9, 2010, in

Vehicle Technology programs at Sandia share a common goal: reducing dependence on petroleum-based fuels and developing sustainable alternative fuels and increased efficiency of vehicle technologies. The United States is at a critical juncture where pressing issues in energy security, climate change, and economic competitiveness are converging.  Aggressive national goals for reducing petroleum use by 25 […]
