Depletion of nonlinearity in two-dimensional turbulence

Article in Phys. Fluids (2014)

Depletion of nonlinearity in two-dimensional turbulence

Andrey V. Pushkarev & Wouter J. T. Bos

The strength of the nonlinearity is measured in decaying two-dimensional turbulence, by comparing its value to that found in a Gaussian field. It is shown how the nonlinearity drops following a (...)

Extremely long Kelvin‐Helmholtz billow trains in the Romanche Fracture Zone

Article in Geophys. Res. Lett. (2014)

Extremely long Kelvin‐Helmholtz billow trains in the Romanche Fracture Zone

Hans van Haren, Louis Gostiaux, Eugene Morozov & Roman Tarakanov

In the Atlantic Ocean, the densest water mass Antarctic Bottom Water “AABW” can only cross the Mid‐Atlantic Ridge from its southwestern to northeastern basins in limited, because deep, conduits. At (...)

Self-organization of helically forced MHD flow in confined cylindrical geometries

Article in Fluid Dyn. Res. (2014)

Self-organization of helically forced MHD flow in confined cylindrical geometries

Malcolm Roberts, Matthieu Leroy, Jorge Morales, Wouter Bos & Kai Schneider

The dynamics of a magnetically forced conducting fluid in confined geometries is studied. A pseudospectral method with volume penalisation is used to solve the resistive magnetohydrodynamic (...)

Introduction of longitudinal and transverse Lagrangian velocity increments in homogeneous and isotropic turbulence

Article in Europhys. Lett. (2014)

Introduction of longitudinal and transverse Lagrangian velocity increments in homogeneous and isotropic turbulence

Emmanuel Lévêque & Aurore Naso

Based on geometric considerations, longitudinal $(\delta u_\parallel^(L)(\tau))$ and transverse $(\delta u_\perp^(L)(\tau))$ Lagrangian velocity increments are introduced as components along, and (...)
