Numerical investigations on interactions between tangles of quantized vortices and second sound.

摘要: The reconnecting vortex-tangle model is used to investigate the interaction of tangles quantized vortices with second sound. This can be expressed in terms an effective line-length density, which depends on direction second-sound wave. By comparing densities various directions tangle structure examined. Simulations were done for flow channels square and circular cross sections as well slits. results show that all these cases are inhomogeneous space. calculated inhomogeneities agreement experiment.
