Fully Coupled Two-Fluid Dynamics in Superfluid ${}^4$He: Anomalous Anisotropic Velocity Fluctuations in Counterflow

Satoshi Yui, Hiromichi Kobayashi, Makoto Tsubota +1

We investigate the thermal counterflow of the superfluid ${}^4$He by numerically simulating three-dimensional fully coupled dynamics of the two fluids, namely quantized vortices and…
