Scaling of locally averaged energy dissipation and enstrophy density in isotropic turbulence

Scaling of locally averaged energy dissipation and enstrophy density in isotropic turbulence

Using direct numerical simulations of isotropic turbulence in periodic cubes of several grid sizes, the largest being 8192 ^3 yielding a microscale Reynolds number of 1300, we study the properties of pressure Laplacian to understand differences in the inertial range scaling of enstrophy density and...
