ABSTRAKT

The results of computational investigations of a steady-state super-fluid helium (He-II) flow in a horizontal cylindrical capillary in the presence of a longitudinal heat flux and in a superfluid vortex flow regime are presented. To describe the He-II flow, the equations of the Landau two-velocity hydrodynamics and the Gorter−Mellink mutual friction theory are used. Analytical solutions of the problem are obtained. An analysis of the solutions shows that the direction of the He-II flow depends on the capillary diameter and heat flux density. The conditions of the He-II flow to a heat source have been determined.
