Gases and liquids are working fluids in many industrial processes and plants for energy conversion. Consequently, the simulation of fluid flows represents a precious support for the design of components and industrial systems. Early theoretical applications of CFD models date from the end of the nineties to develop new algebraic two equation turbulence models. Since then, the research activity has extended to industrial applications, to study and improve the performance of heat-exchangers, racing wheels, and several manufacturing processes. Specific skills were developed in the simulation of turbomachinery (especially fans), ICE manifolds and valves, and combustion systems (burners and industrial combustors), as specified in the description of the other research topics.
