Elastic turbulence in straight confined geometries
Giulio Foggi Rota, Daulet Izbassarov, Aditya Tekriwal +1
Elastic turbulence (ET) in straight geometries has been extensively studied in idealised configurations such as periodic shear and planar channel flow, yet experiments are typicall…
Coexisting chaos and order in micro-textured elastic flows
Giulio Foggi Rota, Ricardo Arturo Lopez de la Cruz, Simon J. Haward +2
Viscoelastic fluid flows over micro-textured surfaces - densely covered by slender protrusions like cilia lining the body airways or villi covering the intestinal epithelium - unde…
Energy transfer and scale organisation in dense canopy turbulence
Riccardo Bertoncello, Alessandro Chiarini, Giulio Foggi Rota +2
This study identifies the scale-dependent processes that sustain turbulence in dense submerged canopy flows. Using a scale-resolved energy budget, we determine where in space and a…
Free surfaces in turbulence - A unified framework from water surfaces to elastic solids
Giulio Foggi Rota, Andrea Mazzino, Marco Edoardo Rosti
What do the ocean surface and a swaying flag have in common? Both are deformable surfaces exhibiting chaotic motion when exposed to turbulent flows. Whether such motion is primaril…
Beyond Stokes drift -- Lagrangian transport in evolving gravity waves
Tatsuo Izawa, Giulio Foggi Rota, Alessandro Chiarini +1
Finite-amplitude gravity waves at the air-water interface induce net fluid and particle transport, known as Stokes drift. While this mechanism is well understood for steady waves,…
Effect of submerged vegetation on water surface geometry and air-water momentum transfer
Giulio Foggi Rota, Alessandro Chiarini, Marco Edoardo Rosti
Understanding how submerged vegetation modifies the water surface is crucial for modeling momentum exchange between shallow waters and the atmosphere. In particular, quantifying it…
Filament inclination effect on turbulent canopy flows
Shane Nicholas, Mohammad Omidyeganeh, Alfredo Pinelli +3
Inspired by the spontaneous behaviour observed in filamentous layers -- where the balance between flow-induced drag and structural elasticity dictates the filaments' equilibrium st…
The broken link between space and time in elastic turbulence
Giulio Foggi Rota, Rahul K. Singh, Alessandro Chiarini +4
Elastic turbulence (ET), observed in flows of sufficiently elastic polymer solution at small inertia, is characterized by chaotic motions and power-law scaling of energy spectrum (…
Forced and natural dynamics of a clamped flexible fiber in wall turbulence
Giulio Foggi Rota, Morie Koseki, Riya Agrawal +2
We characterize the dynamical behavior of a clamped flexible fiber immersed in wall turbulence over a wide range of natural frequencies by means of direct numerical simulations. On…
A unified view of elastic and elasto-inertial turbulence in channel flows at low and moderate Reynolds numbers
Giulio Foggi Rota, Christian Amor, Soledad Le Clainche +1
The chaotic flow of elastic fluids at low Reynolds number (Re) is typically distinguished into elasto-inertial and elastic turbulence (EIT/ET). However, the clear separation among…
