Abstract
This thesis probes possible mechanisms behind anomalous freedecays commonly observed in superfluid helium third sound flows. Several models, based on vortex dissipation, for the additional dissipation these anomalous freedecays imply are constructed, tested, and modified to be consistent with the observed characteristics. This work concludes that these simple models involving only vortex friction and a creation energy are insufficient to explain the observed characteristics. From this conclusion a model is proposed that holds promise for future study.
