 TOUPIE is a large-scale liquid helium wind-tunnel. It has been specially designed to explore quantum turbulence at very large Renolds numbers.


Uniqueness in Europe:

  •  World’s longest superfluid wind-tunnel (1-m-long wind-tunnel)
  • Record superfluid fraction at high Re (temperature down to 1.2 K : 97% superfluid fraction)


Areas of research supported:

  • Quantum turbulence / Superfluid turbulence : He-II co-flows and counter-flows
  • High Re classical turbulence.
