FLUMACS

Our Research...

The research group FLUMACS (FLUid dynamics of MAcro and micro Complex Systems) is based at the Mechanical and Aerospace Department, Sapienza University of Rome working on the fluid dynamics of complex flows. The group is presently growing thanks to the ERC-Advanced-GRANT 2013, BIC (Following bubbles from inception to cavitation).

The group's modus operandi is chiefly theoretical and numerical, oriented to fundamental and numerical modelling. This approach brought us in contact with several neighbouring disciplines, such as physics, material science, chemistry, and biology. The issuing multidisciplinary and multiscale expertise already proved successful in dealing with such diverse problems as Combustion, Drag reduction, Particle Transport, Multiphase Flows, and Interfacial Phenomena like wetting and liquid slippage.

Major achievements of the research group concern the general problem of coupling macroscopic flows with a microstructure. In particular, the group has given contributions in particulate turbulent flows, polymers-laden and multiphase flows. Using DNS, significant insight has been provided in the characterization of turbulent kinetic energy fluxes in wall-bounded flows, where certain exotic effects of reverse energy cascade associated with the so-called coherent structures of vorticity were found fundamental for successful LES of wall-bounded flows. Another field of interest is bubble/droplet nucleation induced by thermal fluctuation by a novel approach which conjugates classical fluid dynamics with fluctuating hydrodynamics.
