Observation of laminar and turbulent flow in superfluid He-4 using a vibrating wire
We have investigated the laminar and the turbulent flow in superfluid 4He using a vibrating wire made of thin NbTi (φ 2.5 μm). The wire velocity as a function of applied force has shown a large hysteresis at the first cooling from normal fluid to the superfluid state. But after a couple of increasin...
