Research interests

My main research interests are focused on the kinetic modeling of pyrolysis, oxidation and combustion processes and on fluid dynamic analyses of devices for combustion processes. In particular, my current research activities cover the following fields:

Interactions between turbulence and kinetics: coupling between detailed kinetics and complex fluid dynamics to predict and to study the formation of pollutant species (unburned hydrocarbons, aldehydes, PAHs, NOx and soot) in combustion devices (combustors for aeromobiles, burners, industrial furnaces, etc.). The main goals are the understanding of physical and chemical phenomena occurring in combustion processes and the creation of new and more efficient combustion devices, characterized by a reduction of pollutant emissions. In this context large attention is devoted to the problem of interactions between turbulence and chemistry, to better understand the effects of turbulent fluctuations on the formation of pollutant species.

Energy and transports: kinetic modeling and fluid dynamic analyses of internal combustion engines and new engines (low temperature oxidation mechanisms, cool flames, autoignition and knocking, evaporation and autoignition of fuel droplets, etc.). At present, particular attention is devoted to the definition of surrogate mixtures to mimic the combustion behavior of real transportation fuels.
