Prof. Riccardo Mereu obtained his Ph.D. in Energy at Politecnico di Milano (POLIMI) with a numerical study about a Non-Linear Eddy Viscosity Model for turbulent flows and his Mechanical Engineering MSc at the University of Cagliari with an experimental and numerical investigation of multi-effect solar still for salt water distillation. His main interests are fluid dynamics and heat transfer phenomena in single- and multiphase flows in industrial and nuclear fields, with particular attention to turbulence and multiphase modeling. Since 2009, he has worked as a Researcher at the CFDLab of the Department of Energy of Politecnico di Milano on parallel confined jet modeling via a Large Eddy Simulation approach. This work, part of the international IRIS nuclear project, was developed in collaboration with Ninokata's Laboratory (Nuclear Department) of the Tokyo Institute of Technology, where he spent a few months from May to September 2009 as a Visiting Researcher. Since March 2010, he has been a two-year Progetto Rocca Post-Doc Fellow at Massachusetts Institute of Technology (MIT)—POLIMI to perform a numerical investigation about Critical Heat Flux (CHF) phenomenon in the nuclear field. Since 2007, he has been a member of Engineering Without Borders—Milan (ISF-MI) in the Energy Group and PM of the project 'CdF Médina' for ISF-MI, focused on the use of appropriate technologies in the energy field. From 2008 to 2010, he was a member of the board and Vice-President of the association.
