Dynamics of the velocity fluctuations in sedimenting suspensions of rigid fibres
Alessandro Chiarini, Emanuele Gallorini, Marco Edoardo Rosti
We use direct numerical simulations to investigate fluid-solid interactions in suspensions of rigid fibres settling under gravity in a quiescent fluid. The solid-to-fluid density r…
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 (…
Understanding the effect of wall elasticity in turbulent channel flows
M. Koseki, M. S. Aswathy, M. E. Rosti
This study compares turbulent channel flows over elastic walls with those over rough walls, to explore the role of the dynamic change of shape of the wall on turbulence. The compar…
Edge-effects in the turbulent flow over flexible aquatic vegetation
Giulio Foggi Rota, Elisa Tressoldi, Francesco Avallone +1
Riparian vegetation along riverbanks and seagrass along coastlines interact with water currents, significantly altering their flow. To characterise the turbulent fluid motion along…
Elastic turbulence hides in the small scales of inertial polymeric turbulence
Piyush Garg, Marco Edoardo Rosti
Gaining a fundamental understanding of turbulent flows of dilute polymer solutions has been a challenging and outstanding problem for a long time. In this letter, we examine homoge…
The effect of shear-thinning on the scalings and small-scale structures of turbulence
Marco Edoardo Rosti
We study the homogeneous isotropic turbulence of a shear-thinning fluid modeled by the Carreau model and show how the variable viscosity affects the multiscale behaviour of the tur…
Bubbles-induced transition to elasto-inertial turbulence
Hafiz Usman Naseer, Daulet Izbassarov, Marco Edoardo Rosti +1
Interface-resolved direct numerical simulations are performed to investigate bubble-induced transition from laminar to elasto-inertial turbulent (EIT) state in a pressure-driven vi…
