Abstract
► Two mechanisms of transition of the superfluid liquid 4He to quantum turbulence regimes are proposed. ► In the roton mechanism the critical velocity depends on channel size as vc∝d−1/4, matching the experiments. ► For the second, super-flow mechanism the critical velocity depends on d as vc∝d−1.
