Numerical Study of the Effect of Freestream Turbulence on by-pass Transition in a Boundary Layer [PDF]
, 2014 We use direct numerical simulations in the presence of free-stream turbulence having different values of intensity, T u, and integral length scale, L, in order to determine which kind of structures are involved in the path to transition of a boundary ...

On the Formation of Super-Alfvénic Flows Downstream of Collisionless Shocks
The Astrophysical JournalSuper-Alfvénic jets, with kinetic energy densities significantly exceeding that of the solar wind, are commonly generated downstream of Earth's bow shock under both high- and low-beta plasma conditions. In this study, we present theoretical evidence that

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations [PDF]
, 2001 We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

Spectral Anisotropy at Ion Scales in the Solar Wind Upstream of the Martian Bow Shock
The Astrophysical JournalThe spectral anisotropy of magnetic field fluctuations at ion scales in the solar wind upstream of the Martian bow shock remains poorly understood. In the solar wind near the Earth’s orbit, such anisotropy is known to be modulated by ion-scale waves ...

MMS Observations of Electron Vorticity in the Earth’s Magnetosheath
The Astrophysical JournalThe Earth’s magnetosheath serves as a natural laboratory to study the transition of highly turbulent fluctuations. The fundamental information about plasma turbulences can be examined observationally with the help of electron vorticity measurements. This

A Unifying Perspective on Kolmogorov Cascades in Solar Wind Plasma Turbulence
The Astrophysical JournalIt is argued that Kolmogorov cascades, including those affecting space weather in the solar wind plasma, can effectively be described by realizations of a continuous-time random walk.

Dynamics of Slow Solar Wind Emerging from an Equatorial Coronal Hole
The Astrophysical JournalWe present a three-dimensional reduced magnetohydrodynamics model to depict turbulence induced by Alfvén waves within the slow solar wind originating from an open magnetic field positioned in a coronal hole near the solar equator.
