By Joe Oefelein By combining advanced theory and high-fidelity large eddy simulation, CRF researchers Rainer Dahms and Joe Oefelein have provided new conceptual insights that promise to improve the understanding and prediction of fuel-injection processes at high-pressure diesel engine conditions. Their results, which were corroborated by experiments performed by CRF researchers Lyle Pickett and Julien…
By Robert Barlow 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 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…
In December, Sandia National Laboratories announced the appointment of Bob Hwang as the new director of the Transportation Energy Center, which includes the Combustion Research Facility (CRF). Bob Carling, who served as director of the Transportation Energy Center from 2008 to 2013, retired in December after 37 years at Sandia. Bob Hwang began his Sandia…
