โฆ Synopsis
The thermal resistance in both superfluid phases of 3He has been measured at 20.0 and 29.6 bar in zero magnetic field. Heat conduction in 3He-B is shown to be primarily hydrodynamic, and a regime of reproducible heat flow behavior in the A phase is reported. The viscosity of each phase as a function of temperature is calculated using an equation of the two-fluid model, and critical velocity effects are discussed.

We discuss the first computer simulations for superfluid vortex formation in 3He flow through narrow channels. Overall features of the phase slippage processes through vortex motion are found to be independent of details in the boundary conditions: diffusive and specular cases exhibit the same scen
