FP4-ENV 2C, Chemistry and Microphysics of Contrail Formation

Description: General Information: The chemistry and microphysics of contrail formation of modern turbojet aircraft engines will be studied using a combined approach of experiments and calculations. The detailed objectives of this proposal are: To improve the mechanism of pollutant formation in both the engine nozle and the jet regime of the plume with particular emphasis on those components that are involved in contrail formation (SOx, HOX,NOy and soot); to characterize the chemical and microphysical properties of aircraft engine soot particles after emission and during ageing under simulated plume conditions; to refine existing numerical codes treating homogeneous and heterogeneous nucleation by including non-equilibrium effects and soot activation kinetics. The proposal is suggested to be carried out in three different work packages; WP1: Modelling of HOx, NOX and SOx chemistry in gas turbine and nozzle region measurments; WP2: Physical and chemical characterization of engine emitted soot particles; WP3: Modelling of homogenes and heterogeneous nucleaction. The participants of this project originate from both the experimental (engine emission and laboratory studies) and modelling (chemistry and microphysics) community with extended individual expertises. It is therefore expected that CHEMICON will be conducted successfully and that its results contribute to an improved understanding of contrail formation.
