"Temperature and soot volume fraction profiles" - Soot particles are formed close to the flame front on the rich side - Blanquart, G., Pitsch, H., Fox, R. O., APS/ DFD, Tampa, FL (2006)

"Benzene molecule" - Predicting the formation of the first aromatic species is considered as the most important limiting step in the inception of soot particles.

"Vorticity magnitude profiles" - The high speed swirling annulus flow creates a recirculation zone central to the stability of the flame - Blanquart, G., Pitsch, H., Fox, R. O., APS/ DFD, Tampa, Florida (2006)

"Low Swirl Injector (LSI)" - Complex injector geometries including swirled vanes and central screens are represented with Immersed Boundaries (IB) for improved accuracy and efficiency - Blanquart, G., Knudsen, E., Pitsch, H., APS/DFD, Minneapolis, MN (2009)

"Flame visualization" - Hydrocarbon fuel is injected in a liquid form, atomizes into droplets, evaporates, burns, and finally leads to the formation of pollutants - Courtesy of Prof. Edwards - Stanford University

"Density profile in a Helium plume" - Small scale structures are formed due to Rayleigh-Taylor instabilities and ultimately leads to large scale puffing cycles.
