Linking the Langevin equation to scaling properties of space plasma turbulence at sub-ion scales
Current understanding of the kinetic-scale turbulence in weakly collisional plasmas still remains elusive. We employ a general framework in which the turbulent energy transfer is envisioned as a scale-to-scale Langevin process.

Incompressible magnetohydrodynamic (MHD) turbulence under influences of the Hall and the gyro-viscous terms was studied by means of direct numerical simulations of freely decaying, homogeneous and approximately isotropic turbulence.

Single-wavenumber Representation of Nonlinear Energy Spectrum in Elastic-Wave Turbulence of {F}\"oppl-von {K}\'arm\'an Equation: Energy Decomposition Analysis and Energy Budget [PDF]
A single-wavenumber representation of nonlinear energy spectrum, i.e., stretching energy spectrum is found in elastic-wave turbulence governed by the F\"oppl-von K\'arm\'an (FvK) equation.

Deep-sea turbulence evolution observed by multiple closely spaced instruments
Turbulent mixing in the deep ocean is not well understood. The breaking of internal waves on sloped seafloor topography can generate deep-sea turbulence.

The present study introduces third-order quasi-analytical solutions of a turbulence-modeling equation, where the standard k − ϵ model equation is used because this model is commonly and widely used in engineering applications.

Direct Energy Cascade in Two-Dimensional Compressible Quantum Turbulence [PDF]
We numerically study two-dimensional quantum turbulence with a Gross--Pitaevskii model. With the energy initially accumulated at large scale, quantum turbulence with many quantized vortex points is generated.

Turbulent flow mechanisms in meandering channels with sediment transport
This research aims to investigate the near-bed turbulent flow characteristics in a meandering channel with both mobile bed and immobile bed conditions. Experiments were performed in a prismatic rectangular meandering channel with a non-uniform sand bed ...

The Nature of Subproton Scale Turbulence in the Solar Wind
The nature of subproton scale fluctuations in the solar wind is an open question, partly because two similar types of electromagnetic turbulence can occur: kinetic Alfven turbulence and whistler turbulence.

Implicit large eddy simulations of anisotropic weakly compressible turbulence with application to core-collapse supernovae [PDF]
(Abridged) In the implicit large eddy simulation (ILES) paradigm, the dissipative nature of high-resolution shock-capturing schemes is exploited to provide an implicit model of turbulence.

Hydraulic characteristics of countercurrent jets on adverse-sloped beds
The counter-current jet (CCJ) acts like a reverse surface jet layer covering the free jump surface and has potential applications in the energy dissipation of hydraulic engineering.
