Abstract:
Spatial structures of energy transfers in both the real and Fourier spaces
are investigated by simulating the F\"{o}ppl-von K\'{a}rm\'{a}n (FvK) equation.
Distinctive structures of the stretching-energy field,
which is the bundle of ridges in the real space
and the line segment at small wavenumbers in the Fourier space,
appear in the active phases of turbulent state.
