Energy Department Awards $7M to Advance Hydrogen Storage Systems

On May 19th, the DOE announced $7M for six projects (five in California + PPG Industries in North Carolina) to develop lightweight, compact, and inexpensive advanced hydrogen storage systems that will enable longer driving ranges and help make fuel-cell systems competitive for different platforms and vehicle sizes. These advances in hydrogen storage will be critical […]

Renewables, Other Energy Issues To Be Focus of Enhanced Sandia-SINTEF Collaboration

Under an expanded agreement, a decades-long partnership between Sandia and the Norwegian research organization SINTEF (Stiftelsen for industriell og teknisk forskning) will now tackle energy challenges such as renewable-energy integration, grid modernization, gas technologies, and algae-based biofuels. SINTEF is the largest independent research organization in Scandinavia, with expertise in the natural sciences and technology, the […]

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 […]

Sandia’s Exascale Computing Effort Expected to Curtail Effects of System Faults

Computing power today is more potent than ever before. Or is it? In many applications, yes, but when it comes to sophisticated, detailed modeling of the Earth’s climate, an analogy of using an abacus to track the national debt may be only a slight exaggeration. “To accurately predict the Earth’s climate over the next 200–300 […]

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 […]
