Quantum turbulence in superfluid 3He-B

Quantum turbulence in superfluid 3He-B

This thesis describes experiments conducted in 3He-B to investigate the properties of quantum turbulence created by an oscillating grid. The turbulence is detected using an array of vibrating wire resonators. We have measured various steady-state properties of the turbulence includ- ing fluctuations...
