Extreme fluctuations of the relative velocities between droplets in turbulent airflow
Ewe-Wei Saw, Gregory P. Bewley, Eberhard Bodenschatz +2
We compare experiments and direct numerical simulations to evaluate the accuracy of the Stokes-drag model, which is used widely in studies of inertial particles in turbulence. We f…
Transition from dissipative to conservative dynamics in equations of hydrodynamics
Debarghya Banerjee, Samriddhi Sankar Ray
We show, by using direct numerical simulations and theory, how, by increasing the order of dissipativity () in equations of hydrodynamics, there is a transition from a dissipati…
Bending dynamics of semi-flexible macromolecules in isotropic turbulence
Aamir Ali, Samriddhi Sankar Ray, Dario Vincenzi
We study the Lagrangian dynamics of semi-flexible macromolecules in laminar as well as in homogeneous and isotropic turbulent flows by means of analytically solvable stochastic mod…
Gravity-driven enhancement of heavy particle clustering in turbulent flow
Jeremie Bec, Holger Homann, Samriddhi Sankar Ray
Heavy particles suspended in a turbulent flow settle faster than in a still fluid. This effect stems from a preferential sampling of the regions where the fluid flows downward and…
