Summary

THIS PAPER PRESENTS THE RESULTS OF AN EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER TO HELIUM IN STATIONARY CONDITIONS, IN CONDITIONS OF INCREASE AND DECREASE OF HEAT POWER AT VARIOUS RATES AND WITH PULSE HEATING. HEAT TRANSFER BOTH FROM A FREE SURFACE AND IN A COAXIAL GAP OF 0.5 MM WAS STUDIED. THE EXPERIMENTS WERE CARRIED OUT WITHIN THE RANGE OF LIQUID SATURATION TEMPERATURES FROM 1.94 TO 4.23 K. IT HAS BEEN SHOWN THAT TRANSIENT THERMAL PROCESSES MAY HAVE HIGHER HEAT TRANSFER COEFFICIENTS COMPARED WITH STEADY STATE CONDITIONS. THE MOST PRONOUNCED EFFECT IS OBSERVED UNDER PULSE HEATING CONDITIONS.
