Correlation function and linear response function of homogeneous isotropic turbulence in the Eulerian and Lagrangian coordinates
Takeshi Matsumoto, Michio Otsuki, Takeshi Ooshida +1
We study the correlation function and mean linear response function of the velocity Fourier mode of statistically steady-state, homogeneous and isotropic turbulence in the Eulerian…
