Magnetic reversals in a geodynamo model with a stably-stratified layer
Nicolás Pablo Müller, Christophe Gissinger, François Pétrélis
We study the process of magnetic reversals in the presence of a stably-stratified layer below the core-mantle boundary using direct numerical simulations of the incompressible magn…
Lack of self-similarity in transverse velocity increments and circulation statistics in two-dimensional turbulence
Nicolás Pablo Müller, Giorgio Krstulovic
We study the statistics of longitudinal and transverse structure functions, as well as velocity circulation in the inverse energy cascade of two-dimensional turbulence. By means of…
Velocity circulation intermittency in finite-temperature turbulent superfluid helium
Nicolás P. Müller, Yuan Tang, Wei Guo +1
We study intermittency of circulation moments in turbulent superfluid helium by using experimental grid turbulence and numerical simulations of the Hall-Vinen-Bekarevich-Khalatniko…
Intermittency of velocity circulation in quantum turbulence
Nicolás P. Müller, Juan Ignacio Polanco, Giorgio Krstulovic
The velocity circulation, a measure of the rotation of a fluid within a closed path, is a fundamental observable in classical and quantum flows. It is indeed a Lagrangian invariant…
