Fiber Tracking Velocimetry for two-point statistics of turbulence
Stefano Brizzolara, Marco Edoardo Rosti, Stefano Olivieri +3
We propose and validate a novel experimental technique to measure two-point statistics of turbulent flows. It consists in spreading rigid fibers in the flow and tracking their posi…
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…
Turbulence dictates the fate of virus-containing droplets in violent expiratory events
Marco E. Rosti, Mattia Cavaiola, Stefano Olivieri +2
Violent expiratory events, such as coughing and sneezing, are highly nontrivial examples of a two-phase mixture of liquid droplets dispersed into an unsteady turbulent airflow. Und…
Dispersed fibers change the classical energy budget of turbulence via nonlocal transfer
S. Olivieri, L. Brandt, M. E. Rosti +1
The back-reaction of dispersed rigid fibers to turbulence is analyzed by means of a state-of-the-art fully-coupled immersed boundary method. The following universal scenario is ide…
Turbulence in a network of rigid fibers
S. Olivieri, A. Akoush, L. Brandt +2
The effect of a network of fixed rigid fibers on fluid flow is investigated by means of three-dimensional direct numerical simulations using an immersed boundary method for the flu…
