Lagrangian velocity statistics of homogeneous isotropic turbulence in dilute polymer solutions
Yusuke Koide, Susumu Goto
We conduct direct numerical simulations of homogeneous isotropic turbulence in dilute polymer solutions to investigate the Lagrangian velocity statistics. We show how polymers modu…

Relationship between the power spectral density of the Lagrangian velocity and the hierarchy of coherent vortices in turbulence
Yusuke Koide, Susumu Goto
We conduct direct numerical simulations of developed turbulence in a periodic cube to investigate the formation mechanism of the power spectral density of the Lagrangian velocity.…
