Modelling of sulphuric acid aerosols in an engine plume
Using one-way-coupled turbulent diffusivity and appropriate microphysical models
This research investigates the formation, growth, and size distribution of H2SO4 aerosols in aircraft engine plumes. It aims to enhance calculations by incorporating spatial variation and turbulence modeling. The study develops a toolchain using AER 3-D software, sets up a CFD model of an engine wake, and couples it with microphysics and advection schemes. The toolchain compares the AER 3-D microphysics model with state-of-the-art box models, showing its effectiveness in handling high H2SO4 concentrations and producing similar size distribution results. Using ANSYS, an axisymmetric engine wake field is calculated, revealing that condensation and nucleation occur in the injection area and wake boundary layer, while coagulation primarily occurs inside the wake. Turbulence influences aerosol diffusion and growth, resulting in size variations with distance from the wake center. The research emphasizes the importance of incorporating spatial variation and turbulence modeling for accurate aerosol predictions.
