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 Basic Energy Sciences (BES) Chemical Sciences Program explores fundamental research in focused areas chemistry relevant to DOE missions. The focus of the Chemical Sciences research at Sandia is the production of energy from chemical processes, principally combustion. In addition to supporting research at Sandia, Chemical Sciences constructed and runs the Combustion Research Facility (CRF). […]
