Summary

TRANSIENT BOILING HEAT TRANSFER CHARACTERISTICS OF R113 AT LARGE STEPWISE POWER GENERATION ARE INVESTIGATED EXPERIMENTALLY OVER A WIDE RANGE OF SYSTEM PRESSURES. THE EXPERIMENTAL RESULTS ARE SUMMARIZED AS FOLLOWS: (1) THERE IS A LIMITING VALUE OF HEAT FLUX, NAMED TRANSIENT CRITICAL HEAT FLUX, ABOVE WHICH THE EFFECTIVE HEAT REMOVAL IN TRANSIENT NUCLEATE BOILING CANNOT BE EXPECTED AND THE TRANSIENT CRITICAL HEAT FLUX BECOMES LOWER THAN THE CRITICAL HEAT FLUX IN THE STEADY STATE UNDER A LOW SYSTEM PRESSURE ; (2) IN THE CASE OF THE LOW SYSTEM PRESSURE, THE INITIAL BUBBLES UNDER THE CONDITION OF NEAR TRANSIENT CRITICAL HEAT FLUX HAVE THE PECULIAR SHAPE LIKE A < STRAW HAT >.
