Summary

THE USAGE OF SUPERFLUID HELIUM (HELIUM II) HAS CRUCIAL IMPORTANCE TO SPACE BORNE COOLING SYSTEMS SUCH AS INFRARED TELESCOPES. IT IS NECESSARY TO SEPARATE HELIUM VAPOUR FROM LIQUID IN ZERO GRAVITY STATE FOR A LONG TIME CONTAINMENT OF HELIUM II IN TANKS. A POROUS PLUG IS ONE OF SUCH SPACE BORNE PHASE SEPARATING DEVICES. FUNDAMENTAL FLOW CHARACTERISTICS OF HELIUM II THROUGH PLUGS ARE STUDIED EXPERIMENTALLY. THE FLOW OF HELIUM II THROUGH A POROUS PLUG WAS SYSTEMATICALLY INVESTIGATED TO UNDERSTAND THE GENERAL FLOW FEATURE AND ALSO TO GET DESIGN DATA.
