I am an researcher at University of Rome Niccolò Cusano, where I am also in charge of teaching two MsC courses.My research is mainly addressed to numerical simulation of complex flows with lattice Boltzmann method.My experience is related to porous media simulation, multiphase flows analysis, fluid-structure interaction, thermal simulations.I have also developed some numerical codes for fuel cells electro-chemical analysis.

In the last two decades, a new class of mesoscopic methods, based on minimal lattice formulation of Boltzmann kinetic equation, has gained significant interest as an efficient alternative to continuum methods based on the discretisation of the NS equations for non ideal fluids. In this paper, three different multiphase models based on the lattice Boltzmann method (LBM) are discussed, in order to assess the capability of the method to deal with multiphase flows on a wide spectrum of operating conditions and multiphase phenomena. In particular, the range of application of each method is highlighted and its effectiveness is qualitatively assessed through comparison with numerical and experimental literature data.

The numerical simulations of the Rayleigh-Taylor instability confirm the capability of Lee's method to reproduce literature results obtained with previous Lattice-Boltzmann models

Great expectations have been placed on both simple and hybrid fuel cell plants, thus making necessary the evolution of analysis strategies to evaluate thermodynamic performance, design improvements, and acceleration of new developments. This paper investigates the thermodynamic potential of combining traditional internal combustion energy systems (i.e., gas turbine and internal combustion engine) with a molten carbonate fuel cell for medium- and low-scale electrical power productions with low CO(2) emissions. The coupling is performed by placing the fuel cell at the exhaust of the thermal engine. As in molten carbonate fuel cells the oxygen-charge carrier in the electrolyte is the carbonate ion, part of the CO(2) in the gas turbine flue gas is moved to the anode and then separated by steam condensation. Plant performance is evaluated in function of different parameters to identify optimal solutions. The results show that the proposed power system can be conveniently used as a source of power generation. [DOI:10.1115/1.4002903]
