Viscous spectral energy coupling across scales in generalised Newtonian fluids
Arthur Couteau, Panayotis Dimopoulos Eggenschwiler, Patrick Jenny
We investigate the spectral energy dynamics of turbulent flows with variable viscosity using direct numerical simulation of homogeneous isotropic turbulence of generalised Newtonia…

The influence of energy-containing scales on the distribution of spectral energy transfers
Arthur Couteau, Panayotis Dimopoulos Eggenschwiler, Patrick Jenny
We present computations of individual mode-to-mode energy transfers from direct numerical simulations of homogeneous isotropic turbulence. Unlike previous approaches based on shell…
