  • The project aims at the study of the transport of anisotropic solid particles in turbulent flows. Turbulent flows with dispersed anisotropic particles are ubiquitous in many industrial and natural processes, from papermaking and wastewater treatment to waterfalls and ocean wave breaking. Anisotropic particles bring remarkable complexity to the problem, due to their manifold interactions with the surrounding flow. The aim of the project is to use simulations and experiments to investigate the transport of solid, liquid or gaseous anisotropic particles by turbulence. The goal is to gain insight into important phenomena as particle-particle interaction, re-suspension and preferential concentration, which in turn modify the underlying turbulence and play a role in many engineering and environmental applications.

    In this context, the proposed project will give experimental focus to the transport of micro-fibers, as a representative model to address the issue of micro-plastics present in environment flows. The experiments involve the study of the solid phase in a turbulent channel flow, using advanced experimental tools to investigate the two-way interactions: velocimetry techniques to investigate the fluid phase (PIV, LDV, PTV, LIF, holography) and tracking of fibers in space and time (velocity, deformation). A further aspect of the study regards the interaction of fibers with bubbly flows. In that case, techniques capable of measuring the shape of deformable bubbles, such as volumetric shadowgraphy, are to be implemented and possibly improved.

    The Institute of Marine Engineering collaborates with 4 universities, which contribute to further experimental topics as well as to numerical simulations.
