Thermodynamics of Superfluid Vortex Tangles

David Jou, Maria Stella Mongiovì

Abstract


We consider the main energetic and geometric aspects contributing to the entropy of the vortex tangles appearing in superfluid turbulence, and we propose a simplified model to evaluate them. We consider the tangle and the underlying superfluid system as two different systems, each one in internal quasi-equilibrium, but
exchanging heat with each other. The resulting thermodynamic formalism is studied in two different significative situations.
