DEWAR TO DEWAR MODEL FOR SUPERFLUID HELIUM TRANSFER.

Author(s) : SNYDER H. A.

Type of article: Article

Summary

A MODEL HAS BEEN DEVELOPED TO PREDICT THE FLOW OF HELIUM II BETWEEN A SOURCE AND A RECEIVING DEWAR. THE TRANSFER PATH MAY CONTAIN POROUS PLUGS OR MECHANICAL PUMPS, HEATER SECTIONS, HEAT LEAKS, CONSTRICTIONS DUE TO VALVES, AND BENDS. THE LINE ELEMENTS ARE EASILY RECONFIGURED BY CHANGING THE INPUT DAT THE INPUT CONSISTS OF THE NUMBER OF FINITE ELEMENT CELLS, THE PRESSURE IN EACH DEWAR, THE HEAT INPUT TO EACH SECTION AND THE DIMENSIONS OF EACH SECTION. THE OUTPUT IS THE TEMPERATURE, PRESSURE, FLOW RATE, VELOCITIES AND HEAT FLUX INE I THE MODEL CONVERGES RAPIDLY AND USUALLY REQUIRES 10 TO 15 ITERATIONS. THE PREDICTIONS AGREE WELL WITH EXPERIMENTAL DATA.
