Influence of different mutual friction models on two-way coupled quantized vortices and normal fluid in superfluid He
Hiromichi Kobayashi, Satoshi Yui, Makoto Tsubota
We study the influence of two mutual friction models on quantized vortices and normal fluid using two-way coupled simulations of superfluid He. The normal fluid is affected by…
Imaging the decay of quantized vortex rings to decipher quantum dissipation
Yuan Tang, Wei Guo, Hiromichi Kobayashi +3
Like many quantum fluids, superfluid helium-4 (He II) can be considered as a mixture of two miscible fluid components: an inviscid superfluid and a viscous normal fluid consisting…
Universal anomalous turbulent diffusion in quantum fluids
Satoshi Yui, Yuan Tang, Wei Guo +2
In classical viscous fluids, turbulent eddies are known to be responsible for the rapid spreading of embedded particles. But in an inviscid quantum fluid where the turbulence is in…
Quantum Turbulence Coupled with Externally Driven Normal-Fluid Turbulence in Superfluid He
Satoshi Yui, Hiromichi Kobayashi, Makoto Tsubota +1
The coupled dynamics of quantum turbulence (QT) and normal-fluid turbulence (NFT) have been a central challenge in quantum hydrodynamics, since it is expected to cause the unsolved…
Fully Coupled Two-Fluid Dynamics in Superfluid He: Anomalous Anisotropic Velocity Fluctuations in Counterflow
Satoshi Yui, Hiromichi Kobayashi, Makoto Tsubota +1
We investigate the thermal counterflow of the superfluid He by numerically simulating three-dimensional fully coupled dynamics of the two fluids, namely quantized vortices and…
Numerical Study on Entrance Length in Thermal Counterflow of Superfluid He
Hiromichi Kobayashi, Satoshi Yui, Makoto Tsubota
Three-dimensional numerical simulations in a square duct were conducted to investigate entrance lengths of normal fluid and superfluid flows in a thermal counterflow of superfluid…
