    Research output: Contribution to journalArticlepeer-review


    Flow of liquid 4He through silica aerogel has been studied by means of a torsional oscillator. Preliminary results on the tortuosity and dissipation of the 4He flow in 88%-porous aerogel are compared with earlier measurements on a 92%-porous sample where a transverse sound resonant technique was used. A hydrodynamic model for saturated superfluid helium in porous media is presented and its predictions are compared with the experimental results. © Springer Science+Business Media, Inc. 2005.
