Experimental Exploration of Intense Quantum Turbulence with He-II

The exotic properties of quantum fluids open numerous opportunities to test our understanding of classical turbulence, for example on the role of dissipation and vorticity. However, each type of quantum fluids pose specific experimental challenges when it comes to generate and probe its turbulence. One quantum fluid, superfluid 4He (He-II) has favourable properties that allows to generated very intense quantum turbulence in classical wind-tunnels and stirring cells. In such conditions, a one-to-one direct comparison between classical and quantum turbulences becomes possible. We will present the recent progresses (and stumbling blocks) along this route.
