Thermal Detection of Turbulent and Laminar Dissipation in Vortex Front Motion

, 2012
We report on direct measurements of the energy dissipated in the spin-up of the superfluid component of 3He-B. A vortex-free sample is prepared in a cylindrical container, where the normal component rotates at constant angular velocity.
