Turbulence

Anisotropic turbulence

Energy-flux vectors in rotating turbulence, J. Fluid Mech. 908, A17

Large-scale structures, waves and vortices coexist in anisotropic turbulence systems. We are trying to elucidate the generation and maintenance mechanism of the coexistence of these different kinds of turbulence.

Wave turbulence

Energy transfer in elastic-wave turbulence, Phys. Rev. E 96, 023106

Gravity waves with broad-band spectra can be observed on the surface and inside of the ocean, and in the atmosphere, and are turbulent flows (in a broad sense). We are working on energy transfer between waves, which is one of the important elements of atmospheric and oceanic flows.
