Abstract

We have measured the rate of energy dissipation in superfluid helium film flow in an attempt to test a recent theory due to Harris-Lowe, which predicts that for superfluid stream velocitiesvsthat just exceed the critical velocityvc0, the rate of dissipation is given by an equation of the form Q=C(vs−vc0)3/2. Our experiments at 1.33 K show that the exponent, predicted to be 3/2, is 1.491±0.021.
