On Thursday, March 19, CCRC organized a seminar by its own Named Professor, Dr. Suk Ho Chung. The seminar, which was titled “Soot Formation in Diffusion Flames and PM issues in Advanced Engines”, was held from 3:00 to 5:00 PM at the lecture hall, Al Kindi building, level 5.

Soot formation process is one of the most complex phenomena in thermal engineering involving fuel pyrolysis, incipient ring formation, PAH formation and growth, soot inception, growth, agglomeration and oxidation. Many of chemical reactions are involved in the process and are coupled with flow characteristics. Chemical cross-linking effect in fuel mixtures on soot and PAH formations were discussed for ethylene/propane  fuels and surrogate fuels,

Soot formation process is one of the most complex phenomena in thermal engineering involving fuel pyrolysis, incipient ring formation, PAH formation and growth, soot inception, growth, agglomeration and oxidation.  Many of chemical reactions are involved in the process and are coupled with flow characteristics. Chemical cross-linking effect in fuel mixtures on soot and PAH formations were discussed for ethylene/propane fuels and gasoline surrogate fuels, along with kinetic mechanism development for PAH growth at the seminar. Sooting limits of various fuels in counter-flow diffusion flames was  introduced together with new sooting metric of sooting temperature index and sooting sensitivity index. Relation with PM issues in advanced engines was also discussed.
