A discussion is given of models for the rotation of helium II involving regions of concentrated vorticity, and it is shown thermodynamically that an arrangement of vortex lines is energetically preferable to an arrangement of vortex sheets. It is suggested that such models exhibit the property of mutual friction, owing to the possibility of collisions between normal fluid excitations and the regions of concentrated superfluid vorticity; the observed anisotropy of this mutual friction (part I of… Expand

Dynamics of a rectilinear vortex in liquid helium II
Steady flow in the neighbourhood of a vortex line in liquid helium II is examined on the basis of Landau's equations of motion and directly from momentum considerations. It is shown that, inExpand
