Dynamics and fluid-structure interaction in turbulent flows within and above flexible canopies
Giulio Foggi Rota, Alessandro Monti, Stefano Olivieri +1
Flexible canopy flows are often encountered in natural scenarios, e.g., when crops sway in the wind or when submerged kelp forests are agitated by marine currents. Here, we provide…
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…
Morphology of clean and surfactant-laden droplets in homogeneous isotropic turbulence
Ianto Cannon, Giovanni Soligo, Marco E. Rosti
We perform direct numerical simulations of surfactant-laden droplets in homogeneous isotropic turbulence with Taylor Reynolds number of 180. The droplets are modelled using the vol…
On-off pumping for drag reduction in a turbulent channel flow
Giulio Foggi Rota, Alessandro Monti, Marco E. Rosti +1
We show that the energy required by a turbulent flow to displace a given amount of fluid through a straight duct in a given time interval can be reduced by modulating in time the p…
Extensional rheometry of mobile fluids. Part II: Comparison between the uniaxial, planar and biaxial extensional rheology of dilute polymer solutions using numerically-optimized stagnation point microfluidic devices
Simon J. Haward, Stylianos Varchanis, Gareth H. McKinley +2
In Part I of this paper [Haward et al. submitted (2023)], we presented a new three-dimensional microfluidic device (the optimized uniaxial and biaxial extensional rheometer, OUBER)…
Extensional rheometry of mobile fluids. Part I: OUBER, an optimized uniaxial and biaxial extensional rheometer
Simon J. Haward, Francisco Pimenta, Stylianos Varchanis +4
We present a numerical optimization of a "6-arm cross-slot" device, yielding several three-dimensional shapes of fluidic channels designed to impose close approximations to ideal u…
Vortex breakdown in the shear-driven flow in a rectangular cavity
H. Wang, X. Yu, S. T. Chan +3
The vortex dynamics of laminar flow past a rectangular cavity is investigated using simulations and experiments. The flow is three-dimensional and characterized by a large, dominan…
Saving Energy in Turbulent Flows with Unsteady Pumping
Giulio Foggi Rota, Alessandro Monti, Marco E. Rosti +1
Viscous dissipation causes significant energy losses in fluid flows; in ducts, laminar flows provide the minimum resistance to the motion, whereas turbulent currents substantially…
Enhanced axial migration of a deformable capsule in pulsatile channel flows
Naoki Takeishi, Marco Edoardo Rosti
We present numerical analysis of the lateral movement of a deformable spherical capsule in a pulsatile channel flow, with a Newtonian fluid in almost inertialess condition and at a…
