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.

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...
