3D Diagnostics
Page • Many reacting flows are inherently three dimensional and temporally evolving. High-speed 3D imaging measurements are required to capture the dynamics of key processes such as localized extinction and re-ignition in turbulent combustion. To meet that need, we have combined multi-kHz rate tomographic particle image velocimetry (tomo-PIV) and laser-induced fluorescence (LIF)...

A New Concept for Time-Resolved Fourier-Transform Spectroscopy
Post, November 22, 2013 • In developing the dual etalon frequency comb (DEFCOM) spectrometer, CRF researchers Haifeng Huang and David Chandler are refining a new concept for time-resolved Fourier-transform (FT) spectroscopy based on the interference between two transient frequency combs.

Assessing the economic potential of advanced biofuels
Post, April 9, 2013 • Dean Dibble (8237) prepares samples of switchgrass for analysis. (photo by Randy Wong) Biofuels hold great promise for the future of transportation energy, but the day that biofuel completely replaces gasoline at the pump is still a long way off. How far off is, at best, an educated guess, with...

Characterizing the development of thermal stratification in HCCI engines
Post, May 16, 2011 • Homogeneous charge compression ignition (HCCI) engines can deliver high efficiencies—comparable to a diesel engine or higher—and ultra-low NOx and particulate emissions. They also offer the potential for lower cost than diesel engines and do not require expensive diesel-emissions after treatment for a significantly lower overall package price. HCCI is therefore...
