Tk. Lesniewski et al., ON HE-II INERTIA EFFECTS IN SHORT NARROW DUCTS - ENTRANCE EFFECTS ASSOCIATED WITH BOUNDARY-LAYER DEVELOPMENT, Cryogenics, 36(3), 1996, pp. 203-207
The possibility of a He II counterflow laminar boundary layer in short
narrow ducts with adiabatic lateral walls is considered. There is sub
stantial support for laminar boundary layer-mediated counterflow trans
port at zero net mass flow in porous media.
