Aircraft contrails may contribute to the global radiative forcing. In this context, the investigation of contrail formation in the near field of an aircraft engine may be helpful in developing numerical models to reduce undesirable impacts. This study is based on three-dimensional CFD simulations with an ice microphysics module in order to investigate the ice particles formation and evolution behind a complex geometry of an aircraft engine involving a bypass and a core flow. The Unsteady Reynolds-Averaged Navier-Stokes equations are used to model the flow. Particles emitted from the engine are tracked with a Lagrangian approach accounting for ice particles growth. The simulations were carried out under realistic operation conditions for two aircraft engines: the CFM56-3 and the LEAP-1A, a recent one. The model can differentiate the formation threshold of ice particles between both engines (26 % earlier in term of distance for the LEAP-1A). Then, larger mean ice particles are found at the end of the simulation for the LEAP-1A (20 % larger). Finally, the results show that the optical depth is higher for the CFM56-3 (360 % higher).<\/p>","protected":false},"excerpt":{"rendered":"
