TRANSIENT SUPERCONDUCTOR (NIOBIUM-TITANIUM/COPPER)-HELIUM II HEAT TRANSFER RATES TO PRESSURIZED SUPERFLUID DURING STEP INPUT IN POWER.

Summary

TRANSIENT THERMAL BOUNDARY CONDITIONS HAVE BEEN STUDIED FOR THE SYSTEM NIOBIUM-TITANIUM/COPPER-SUPERFLUID AT AND ABOVE ATMOSPHERIC PRESSURE, INCLUDING THE SUPERFLUID THERMOHYDRODYNAMICS. THE COMPOSITE SUPERCONDUCTOR HAS APPROXIMATELY SQUARE CROSS SECTION (0.2 X 0,2 CM2 ). THE SURFACE POWER DENSITY IS FOUND TO BE A MONOTONICALLY DECREASING FUNCTION OF TIME, Q(T), FOR COMPOSITE ISOTHERMS DURING STEP INPUT IN POWER AT A CONSTANT BATH TEMPERATURE. THE ISOTHERMS ARE TERMINATED AT THE REGIME BOUNDARY OF NON-BOILING HELIUM II.
