Superfluid Turbulence : The TOUPIE experiment
TOUPIE wind-tunnel pictures
Main design characteristics
- Liquid helium wind-tunnel, He-I and He-II compatible
- Pressurized to avoid cavitation in He-I
- Operation from 4K down to 1.1 K
- test-section : straight pipe, 90-cm-long and diameter up to 9-cm
This experiment has been cooled down for the first time in July 2010.

This work is a collaboration with G. Garde (design, fabrication, coordination of assembling, cryogenic tests...), P. Chanthib (in particular for the challenging pumping lines), P.-L. Delafin, J. Depont, E. Ghiringheli, assisted by Pr Guillet and Pr Kueny (ENSE3) for optimisation of parts of the wind-tunnel (cryogenic pump, ...).
