Type of article: Article

Summary

THE INFLUENCE OF FORCED FLOW ON THE HELIUM I-HELIUM II TWO-PHASE FLOW HAS BEEN STUDIED DURING HEAT TRANSFER TO SUPERFLUID HELIUM II IN A U-SHAPED TUBE, AT PRESSURES FROM 2.4 TO 10 BAR, BATH TEMPERATURES FROM 1.6 TO 2.1 K, AND FLOW VELOCITIES FROM < ZERO NET MASS FLOW > TO 0.1 CM/S. FORCED FLOW (I) DID NOT INFLUENCE HEAT TRANSFER PRIOR TO PHASE TRANSITIONS MORE THAN 10% ; (II) REDUCED TEMPERATURE EXCURSIONS AT LAMBDA PHASE TRANSITIONS BY A FACTOR OF TWO AT MOST WITH RESPECT TO ZERO NET MASS FLOW ; (III) DID NOT INFLUENCE THE LIMITING HEAT FLUX DENSITY AT INITIATION OF THE LAMBDA TRANSITION.
