The experimental results are compared with those obtained in analogous experiments with classical fluids and with preliminary simulations of the quantum turbulence. Particular attention is paid to observed values of drag coefficients and to the very different critical velocities observed in ~4He and ~3He. It is tentatively concluded that in the case of ~4He behavior may well be similar to that observed in the classical analogues, with relatively small changes when the characteristic size of the oscillating structure is not large compared with the quantized vortex spacing, but that in the case of ~3He behavior is very different and due perhaps to very rapid intrinsic nucleation of the quantized vortices. 收起
