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…
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…
Inertial focusing of spherical capsule in pulsatile channel flows
Naoki Takeishi, Kenta Ishimoto, Naoto Yokoyama +1
We present numerical analysis of the lateral movement of spherical capsule in the steady and pulsatile channel flow of a Newtonian fluid, for a wide range of oscillatory frequency.…
2.5D turbulence in shear-thinning jets
Christian Amor, Giovanni Soligo, Andrea Mazzino +1
The dimensional transition in turbulent jets of a shear-thinning fluid is studied via direct numerical simulations. Our findings reveal that under vertical confinement, the flow ex…
From yield stress to elastic instabilities: Tuning the extensional behavior of elastoviscoplastic fluid
Mohamed S. Abdelgawad, Simon J. Haward, Amy Q. Shen +1
In this study, we delve into the intricacies of elastoviscoplastic (EVP) fluids, particularly focusing on how polymer additives influence their extensional behavior. Our findings r…
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…
Laminar planar jets of elastoviscoplastic fluids
Giovanni Soligo, Marco Edoardo Rosti
We perform numerical simulations of planar jets of elastoviscoplastic (EVP) fluid (\citet{saramito2007new} model) at low Reynolds number. Three different configurations are conside…
The dynamics of fibers dispersed in viscoelastic turbulent flows
M. S. Aswathy, Marco E Rosti
This study explores the dynamics of finite-size fibers suspended freely in a viscoelastic turbulent flow. For a fiber suspended in Newtonian flows, two different flapping regimes w…
