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

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…

CRF Research Demonstrates Wide Appeal

Adding to the numerous citings of CRF papers in the past, two new examples confirm the value that others place on our work. While visiting the website of the Proceedings of the Combustion Institute, a biennial publication at the forefront of combustion science, Sandia Senior Scientist John Dec of the Transportation Energy Center discovered that…
