Non-equilibrium turbulent transport in convective plumes obtained from closure theory
Nobumitsu Yokoi
Non-equilibrium property of turbulence modifies characteristics of turbulent transport. With the aid of response-function formalism, such non-equilibrium effects in turbulent trans…

Transport in helical fluid turbulence
Nobumitsu Yokoi
Kinetic helicity (hereafter helicity) is defined by the correlation between the velocity and the flow-aligned vorticity. Helicity, as well as energy, is an inviscid invariant of th…

Unappreciated cross-helicity effects in plasma physics: Anti-diffusion effects in dynamo and momentum transport
Nobumitsu Yokoi
The cross helicity (velocity--magnetic-field correlation) effects in the magnetic-field induction and momentum transport in the magnetohydrodynamic (MHD) turbulence are investigate…
