Research interests
My research activity deals with the chemical-kinetic analysis of reacting systems of hydrocarbons, and is ultimately targeted at accommodating the information included in detailed kinetic mechanisms into large-scale computations. For this reason, my research interest is devoted, to a large extent, to the reduction of chemical kinetic mechanisms to a skeletal level, in such a way to allow their use for the numerical applications of interest. Starting from the lumping methodology to model the combustion and pyrolysis of hydrocarbons with a lower number of species, my work in the recent years has been first focused to attaining a further level of reduction through the implementation of approaches based on flux analysis and sensitivity analysis. As a result, a numerical tool for mechanism reduction, called DoctorSMOKE, has been finalized. Acquiring such a capability paved the way to carry out fundamental studies targeted at getting a deeper insight on the interaction between kinetics and fluid dynamics on the ignition behavior and pollutants formation.
