Abstract

The dissipation processes which accompany superfluid flow in saturated helium films have been studied as a function of flow rate, temperature, and film height or thickness. The film flow into or out of a glass beaker was driven at a chosen rate by expanding or compressing bellows which were attached to the bottom of the beaker. The bellows were driven remotely via a hydraulic link to minimize vibration. The cryostat was essentially vibration-free, including elimination of boiling nitrogen from contact with the helium dewar.
