Domains: Optimisation of resources and infrastructure

The formation of polycyclic aromatic hydrocarbons (PAHs) in flames is a key step in the generation of soot particles, major combustion pollutants that are detrimental to public health, as well as being implicated in climate change.  Similar chemistry is also proposed to take place in planetary atmospheres and in the interstellar medium.  Even the initial stages in the chemistry of PAH formation are not well understood. This project is focused on developing an improved description of the PAH formation in flames, particularly the destruction and growth of the first aromatic ring(s).
