Microphysical, chemical, and dynamical processes in aircraft plumes

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


A study was conducted to theoretically investigate the microphysical and chemical processes in aircraft exhaust plumes during the first stages of wake dispersion. A suitable computational model was developed that describes the two-dimensional (2D) turbulent mixing of a single jet of exhaust gas from aircraft engines with the atmosphere. A trajectory box model was also developed that is driven by turbulent mixing rates from the 2D jet model. Following this, a microphysical module was designed and coupled to the box model. Finally, the potential for heterogeneous chemical processing on/in plume and contrail aerosols was determined.
