Isotropic third-order statistics in turbulence with helicity: the 2/15-law
Susan Kurien, Mark A. Taylor, Takeshi Matsumoto
The so-called 2/15-law for two-point, third-order velocity statistics in isotropic turbulence with helicity is computed for the first time from a direct numerical simulation of the…

Lagrangian singularities of steady two-dimensional flow
W. Pauls, T. Matsumoto
The Lagrangian complex-space singularities of the steady Eulerian flow with stream function are studied by numerical and analytical methods. The Lagrangian sing…

Cascade time-scales for energy and helicity in homogeneous isotropic turbulence
Susan Kurien, Mark A. Taylor, Takeshi Matsumoto
We extend the Kolmogorov phenomenology for the scaling of energy spectra in high-Reynolds number turbulence, to explicitly include the effect of helicity. There exists a time-scale…
