Transient inverse energy cascade in free surface turbulence
G. Boffetta, A. Mazzino, S. Musacchio +1
We study the statistics of free-surface turbulence at large Reynolds numbers produced by direct numerical simulations in a fluid layer at different thickness with fixed characteris…
The effect of particle anisotropy on the modulation of turbulent flows
Stefano Olivieri, Ianto Cannon, Marco E. Rosti
We investigate the modulation of turbulence caused by the presence of finite-size dispersed particles. Bluff (isotropic) spheres vs slender (anisotropic) fibers are considered to u…
An Eulerian-based immersed boundary method for particle suspensions with implicit lubrication model
Naoki Hori, Marco Edoardo Rosti, Shu Takagi
We describe an immersed boundary method in which the fluid-structure coupling is achieved in an Eulerian framework. The method is an improved extension of the immersed boundary met…
The effect of droplet coalescence on drag in turbulent channel flows
Ianto Cannon, Daulet Izbassarov, Outi Tammisola +2
We study the effect of droplet coalescence on turbulent wall-bounded flows, by means of direct numerical simulations. In particular, the volume-of-fluid and front-tracking methods…
Universal flapping states of elastic fibers in modulated turbulence
Stefano Olivieri, Andrea Mazzino, Marco E. Rosti
We study the fully-coupled dynamics between a fully-developed turbulent flow and an ensemble of immersed flexible fibers. We vary the concentration of the suspension, the mechanica…
Fluid dynamics of COVID-19 airborne infection suggests urgent data for a scientific design of social distancing
M. E. Rosti, S. Olivieri, M. Cavaiola +2
The COVID-19 pandemic is largely caused by airborne transmission, a phenomenon that rapidly gained the attention of the scientific community. Social distancing is of paramount impo…
