Influence of fuel sulfur on the composition of aircraft exhaust plumes: The experiments SULFUR 1–7

Abstract: The series of SULFUR experiments was performed to determine the aerosol particle and contrail formation properties of aircraft exhaust plumes for different fuel sulfur contents (FSC, from 2 to 5500 μg/g), flight conditions, and aircraft (ATTAS, A310, A340, B707, B747, B737, DC8, DC10). This paper describes the experiments and summarizes the results obtained, including new results from SULFUR 7. The conversion fraction ε of fuel sulfur to sulfuric acid is measured in the range 0.34 to 4.5% for an older (Mk501) … Show more

“…Several areas require further research, including the microphysical and chemical processes governing the evolution of aviation particulates. Previous work has sought to characterize aircraft engine emissions using combustion rigs, on-ground engine tests [4,[6][7][8], and measurements taken in the aircraft engine plumes at altitude [6]. The work described in this paper complements these efforts.…”

“…The number of ice crystals formed initially (during the first second after engine exit), N 00 , depends on the number of soot particles emitted from the engines, the temperature (relative to the threshold temperature for contrail formation) and the fuel sulphur content (Kärcher and Yu, 2009;Schumann et al, 2002;Kärcher et al, 1998;Schumann et al, 1996). Generally, the initial number of ice crystals is of the order 10 12 to 10 13 m −1 .…”

“…The published literature 19 -21 supports that for the short atmospheric residence times in the vicinity of aircraft operations, a best estimate of 3.3% was a reasonable assumption for ε. 20 However, at the time of this writing, a lower default value is being considered based on recent measurements that have not been fully published.…”
