Terese Lovas has been awarded her first EPSRC grant of £302.084. The grant will allow Teresa to undertake research into harmful particulate emissions in urban areas that largely originate from combustion in IC engines. As most practical combustion processes involve the turbulent mixing of gases, the interactions between the turbulent flow field and the chemical processes are important. The study will focus on the effect of preferential diffusion under moderate turbulent mixing, and typical conditions at the end of the combustion phase of in diesel engines when most of particulate emissions are formed. This important new understanding of the effect of preferential diffusion on particle formation will in turn represent the basis of further model development towards implementation into commercial codes for realistic engine simulation.
