Abstract
The usage of superfluid helium (He II) has crucial importance to space borne cooling systems such as infrared telescopes. It is necessary to separate helium vapor from liquid in zero gravity state for a long time containment of He II in tanks. A porous-plug is one of such space borne phase separating devices. Fundamental flow characteristics of He II through plugs are studied experimentally. The flow of He II through a porous-plug was systematically investigated to understand the general flow feature and also to get design data. The feasibility of flow rate control by the use of a heater is also experimentally verified.
