In several numerical and experimental studies [1, 2] on freely evolving or decaying two-dimensional (2D) turbulence on a square bounded domain it is observed that a flow, initially containing no net angular momentum (L), spontaneously acquires angular momentum by flow-wall interaction. From earlier work, by Li and Montgomery , it could be conjectured that on a circular domain with a no-slip boundary angular momentum production is absent. Decaying turbulence experiments in stratified fluids conducted a few years later by Maassen et al.  provided additional evidence supporting this conjecture. These observations have recently been confirmed by Schneider and Farge  for decaying 2D turbulence with substantially higher initial integral scale Reynolds numbers.
