Vortex Line Density in Plane Couette Flow in Superfluid Helium
Abstract
Recent interest in cryogenic applications has enhanced studies in coflow superfluid turbulence, which is characterized by two fluids, normal and superfluid, moving in the same direction. In our studies we are interested to deal with superfluid turbulence in plane Couette flow, as an illustration of this interesting phenomena. An equation previously proposed to describe the evolution of vortex line density in rotating counterflow turbulent
tangles in $^4$He is generalized to incorporate nonvanishing barycentric velocity and velocity gradients. Incorporating our generalized equation into a thermodynamical model previously
proposed, we evaluate the vortex density in plane Couette flow.
