Inhomogeneous distribution of particles in coflow and counterflow quantum turbulence
Inhomogeneous distribution of particles in coflow and counterflow quantum turbulence
Particles are a useful tool for studying superfluid turbulence and visualizing quantum vortices. We study the dynamics of inertial particles in finite-temperature quantum turbulence with the two-fluid Hall-Vinen-Bekarevich-Khalatnikov model. We find that, at low temperatures, when the superfluid mass fraction is dominant, particles cluster on superfluid vortex filaments regardless of …
