Dissipation of mesoscale eddies at a western boundary via a direct energy cascade
Scientific Reports, 2022 The fate of mesoscale eddy kinetic energy represents a large source of uncertainty in the global ocean energy budget. Satellite altimetry suggests that mesoscale eddies vanish at ocean western boundaries.

Turbulent Diffusion of the Particles within Pulsar Wind Nebulae
The Astrophysical Journal, 2023 A turbulent diffusion model is presented to account for the energy and spatial diffusion of the particles within pulsar wind nebulae (PWNe), with the assumption that the energy injected from the pulsar into the nebula is split between the turbulence ...

Magnetically Assisted Vorticity Production in Decaying Acoustic Turbulence
The Astrophysical JournalWe study vorticity production in isothermal, subsonic, acoustic (nonvortical), and decaying turbulence due to the presence of magnetic fields. Using three-dimensional numerical simulations, we find that the resulting kinetic energy cascade follows the ...

A new dynamic subgrid-scale model using artificial neural network for compressible flow
Theoretical and Applied Mechanics Letters, 2022 The subgrid-scale (SGS) kinetic energy has been used to predict the SGS stress in compressible flow and it was resolved through the SGS kinetic energy transport equation in past studies.
