Reconfiguration and dynamics of clamped fibers under finite-amplitude surface gravity waves
Giulio Foggi Rota, Alessandro Chiarini, Marco Edoardo Rosti
We investigate the behaviour of a flexible stem completely submerged under a surface gravity wave of finite amplitude using fully resolved direct numerical simulations. By varying…
Extending Kolmogorov Theory to Polymeric Turbulence
Alessandro Chiarini, Rahul K. Singh, Marco E. Rosti
The addition of polymers fundamentally alters the dynamics of turbulent flows in a way that defies Kolmogorov predictions. However, we now present a formalism that reconciles our u…
Turbulent skin-friction drag reduction via spanwise forcing at high Reynolds number
Davide Gatti, Maurizio Quadrio, Alessandro Chiarini +2
We address the Reynolds-number dependence of the turbulent skin-friction drag reduction induced by streamwise-travelling waves of spanwise wall oscillations. The study relies on di…
Kolmogorov-size particles in homogeneous and isotropic turbulence
Alessandro Chiarini, Simone Tandurella, Marco Edoardo Rosti
We investigate the fluid-solid interaction of suspensions of Kolmogorov-size spherical particles moving in homogeneous isotropic turbulence at a microscale Reynolds number of $Re_λ…
Stability and dynamics of the laminar flow past rectangular prisms
Alessandro Chiarini, Edouard Boujo
The laminar flow past rectangular prisms is studied in the space of length-to-height ratio (), width-to-height ratio () and Reynolds number ($Re…
Finite-size inertial spherical particles in turbulence
Alessandro Chiarini, Marco Edoardo Rosti
We investigate by direct numerical simulations the fluid-solid interaction of non-dilute suspensions of spherical particles moving in triperiodic turbulence, at the relatively larg…
