Mixing of a passive scalar across a thin shearless layer: concentration of intermittency on the sides of the turbulent interface
Autor: Michele Iovieno, Daniela Tordella, Luca Gallana, S. Di Savino
Publikováno v: Journal of Turbulence. 15:311-334
The advection of a passive scalar through an initial flat interface separating two different isotropic decaying turbulent fields is investigated in two and three dimensions. Simulations have been performed for a range of Taylor’s microscale Reynold

Voyager 2 solar plasma and magnetic field spectral analysis for intermediate data sparsity
Autor: Michele Iovieno, John D. Richardson, Sophie M. Fosson, Luca Gallana, Enrico Magli, M. Opher, Federico Fraternale, Daniela Tordella
The Voyager probes are the furthest, still active, spacecraft ever launched from Earth. During their 38-year trip, they have collected data regarding solar wind properties (such as the plasma velocity and magnetic field intensity). Unfortunately, a c

Energy and water vapor transport across a simplified cloud-clear air interface
Autor: F De Santi, Luca Gallana, S. Di Savino, Daniela Tordella, Michele Iovieno
We consider a simplified physics of the could interface where condensation, evaporation and radiation are neglected and momentum, thermal energy and water vapor transport is represented in terms of the Boussinesq model coupled to a passive scalar tra

Cross and magnetic helicity in the outer heliosphere from Voyager 2 observations
Autor: Luca Gallana, Daniela Tordella, John D. Richardson, Michele Iovieno, Federico Fraternale, Merav Opher
Plasma velocity and magnetic field measurements from the Voyager 2 mission are used to study solar wind turbulence in the slow solar wind at two different heliocentric distances, 5 and 29 astronomical units, sufficiently far apart to provide informat

Turbulence in the solar wind: spectra from Voyager 2 data at 5 AU
Autor: Luca Gallana, M. Opher, John D. Richardson, Federico Fraternale, Daniela Tordella, Michele Iovieno
Fluctuations in the flow velocity and magnetic fields are ubiquitous in the Solar System. These fluctuations are turbulent, in the sense that they are disordered and span a broad range of scales in both space and time. The study of solar wind turbule
