Summary

THE PAPER DESCRIBES AND ANALYSES AN ENCLOSED GALLERY DEVICE DESIGNED FOR COLLECTING AND DELIVERING HELIUM II TO A PUMP. THE DEVICE ALLOWS MOST OF THE LIQUID TO MOVE ABOUT IN THE TANK WHILE IT MAINTAINS A LIQUID FLOW TO THE PUMP. ONLY THE LIQUID IN THE SCREEN-COVERED GALLERY CHANNELS AND IN THE UPPER AND LOWER RECEIVERS IS CONTAINED. THE DEVICE OPERATES BY PROVIDING SURFACE TENSION DOMINATED LIQUID PATHS FROM ALL LOCATIONS WITHIN THE TANK TO THE LOWER RECEIVER, WHICH HOUSES THE PUMP. SINCE THE FLUID PRESSURE IN THE CHANNELS MAY BE BELOW THE SATURATED VAPOUR PRESSURE, AN ANALYSIS OF HELIUM II CAVITATION IS PERFORMED TO DETERMINE IF CAVITATION WILL OCCUR.
