Statistics of surface gravity wave turbulence in the space and time domains [PDF]
, 2010 We present experimental results on simultaneous space–time measurements for the gravity wave turbulence in a large laboratory flume. We compare these results with predictions of the weak turbulence theory (WTT) based on random waves, as well as with ...

Survival of 2D Turbulence in the Local Interstellar Medium
The Astrophysical Journal LettersThe evolution of 2D turbulence in the partially ionized local interstellar medium is investigated using 2D MHD simulations coupled with a neutral hydrogen gas via charge exchange.

Advanced Materials Technologies, EarlyView.ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

On Transition in Plasma Turbulence with Multiple Scale Lengths [PDF]
, 2003 A statistical theory of plasma turbulence which is composed of multiple-scale fluctuations is examined. Influences of statistical noise and variance of rapidly-changing variable in an adiabatic approximation are investigated.

von Kármán self-preservation hypothesis for magnetohydrodynamic turbulence and its consequences for universality [PDF]
, 2012 We argue that the hypothesis of preservation of shape of dimensionless second- and third-order correlations during decay of incompressible homogeneous magnetohydrodynamic (MHD) turbulence requires, in general, at least two independent similarity length ...

Enhanced Energy Conversion by Turbulence in Collisionless Magnetic Reconnection
The Astrophysical JournalMagnetic reconnection and turbulence are two of the most significant mechanisms for energy dissipation in collisionless plasma. The role of turbulence in magnetic reconnection poses an outstanding problem in astrophysics and plasma physics.

Global 3D full-scale turbulence simulations of TCV-X21 experiments with SOLEDGE3X
Nuclear Materials and EnergyFirst principle modelling of edge plasma turbulence including neutrals and plasma recycling on the wall remains a challenge, in particular due to the long time scales necessary to simulate to reach particle balance.

The Role of the Plasma Current in Turbulence Decrease with Lower Hybrid Waves
EPJ Web of Conferences, 2017 We study the effect of lower hybrid waves on edge turbulence using a set of two Langmuir probes inserted in the scrape-off layer of the Tore Supra tokamak.

Simulation of the interaction between plasma turbulence and neutrals in linear devices
Nuclear Materials and Energy, 2017 The interaction between plasma and neutrals within a tokamak dominates the behaviour of the edge plasma, especially in the divertor region. This area is not quiescent, but has significant perturbations in the density and temperature due to turbulent ...
