Anisotropic Energy Transfer and Conversion in Magnetized Compressible Turbulence
The Astrophysical Journal, 2023 We present a spatial filtering (or coarse-graining) analysis on 3D magnetized magnetohydrodynamic (MHD) turbulence simulations. The filtered compressible MHD formulae show transfer of kinetic and magnetic energies from large to small scales, as well as ...

Data-driven decomposition of the streamwise turbulence kinetic energy in boundary layers. Part 2. Integrated energy and $A_{1}$ [PDF]
Journal of Fluid Mechanics, 2018 Scalings of the streamwise velocity energy spectra in turbulent boundary layers were considered in Part 1 (Baars & Marusic, J. Fluid Mech., vol. 882, 2020, A25). A spectral decomposition analysis provided a means to separate out attached and non-attached

The energy- and flux budget theory for surface layers in atmospheric convective and stably stratified turbulence [PDF]
Physics of Fluids 34, 116602 (2022), 2021 The energy- and flux budget (EFB) turbulence closure theory for the atmospheric surface layers in convective and stably stratified turbulence has been developed using budget equations for turbulent energies and fluxes in the Boussinesq approximation. In the lower part of the surface layer in the atmospheric convective boundary layer (CBL), the rate of ...

Kinetic Turbulence in Collisionless High-β Plasmas
Physical Review X, 2023 We present results from three-dimensional hybrid-kinetic simulations of Alfvénic turbulence in a high-β, collisionless plasma. The key feature of such turbulence is the interplay between local wave-wave interactions between the fluctuations in the ...
