Principali attività di ricerca e progetti

  • Utilization of alternative fuels as NG/H2 blends/syngas for the transition to a decarbonized fuel in both industrial and domestic applications with focus on innovative combustion technologies as MILD (flameless) combustion. CFD plays a key role, but its application is very challenging because of the need to revise and improve existing models.

  • Fundamental analysis and technological solutions for process intensification using microreactors. Microreactors ensure an unprecedented control of process conditions, thus allowing chemical reactions to be carried out with higher yields, less wastes and energy as well as safer conditions with respect to conventional batch/semi-batch processes used for drug or chemical synthesis. CFD helps to comprehend the mixing and reaction process and the microscale, to face technological barriers.
