Kolmogorov and Kelvin Wave Cascades in a Generalized Model for Quantum Turbulence
The three-dimensional visualisation above shows a close up of the initial condition used in this work. The red low-density isosurface correspond to quantum vortex lines whereas the greenish rendering are density fluctuations about the bulk value.
