experiments indicate that the energy exchange between the asymmetric
and symmetric flows is weaker in the wavenumber 3 case. Nevertheless, a
weak oscillation of the energy transfer is still present near the radius of 0.1,
while in the outer region (

can transfer more energy into the symmetric flows than the corresponding
