Abstract
Under consistent truncation of the Fourier amplitude equations for the inviscid two-dimensional flow, it is shown that the class of extraneous constants of motion associated with Hald’s model examples does not appear. Hence, the conclusion that total energy and enstrophy being the only isolating constants of two-dimensional turbulence is still valid, until a new class of constants of motion is discovered.Keywords
