Reduction of Pah and Soot in Premixed Ethylene-Air Flames by Addition of Dimethyl Ether

Corrigendum to “Reduction of PAH and soot in premixed ethylene–air flames by addition of ethanol” [Combust. Flame 144 (2006) 675–687]

“…[1]) that were so similar that they have raised issues within our research community. This situation is the result of several mistakes on our DOI part, including deciding to publish the work in two papers, submitting those papers to different journals, and failing to cross-reference the papers.…”

“…The purpose of this corrigendum is to rectify, to the extent possible, these mistakes. The paper on the effects of dimethyl ether (DME) on PAH and soot, which was published in the May 2006 issue of Combustion Science and Technology [1], should have referenced the paper that was pub- The fact that the data sets for ethanol and DME are so similar, along with the nearly identical text in the two papers, gives the impression that the two papers are based on the same data. To clarify this issue, Figs.…”

Computational and experimental study of the effects of adding dimethyl ether and ethanol to nonpremixed ethylene/air flames

“…Only five such investigations have been published [14][15][16][17][18]. Four of these studies [14][15][16]18] contain experimental and computational components. The remaining study [17], which contains experimental results only, was written by two of the present work's authors (CSM and LDP); the experimental data contained therein represent a very small subset of the experimental data explored in the present work.…”

“…Increases in benzene led to greater soot production. Wu et al published two studies of premixed flat flames in 2006, adding EtOH [15] and DME [16] to ethylene/air flames and measuring soot volume fraction and PAH fluorescence. Experimentally, they observed a reduction in soot and PAHs as EtOH and DME were added, with the larger reduction occurring when DME was added.…”

Numerical study of the effect of oxygenated blending compounds on soot formation in shock tubes

“…From previous studies [34][35][36][37][38][39][40][41][42], it is known that several alcohol and ether blends are able to suppress engine "knock" and to reduce the amount of polyaromatic hydrocarbons (PAHs) as well as soot formed during the process of combustion. However, none of these studies focused on systematic investigation of a possible change of soot-suppressing into soot-promoting effects of oxygenated blends dependent on their concentration, especially for carbon-rich reaction mixtures, such as for shock tube pyrolysis of aromatic fuels.…”
