Model simulations of fuel sulfur conversion efficiencies in an aircraft engine: Dependence on reaction rate constants and initial species mixing ratios

摘要

The fuel sulfur conversion efficiency εbehind the combustor of aJT9D -7A aircraft engine in flight has been simulated using anextended exhaust plume chemistry model. The model simulations startin the high- temperature intra-engine regime behind the combustor.The simulations show that the sulfur conversion efficiency issensitively dependent on model assumptions like reaction rateconstants and initial mixing ratios. Sensitivity studies todemonstrate the effect of the uncertainties and variabilities ofthese parameters on εare Presented.
