POOL BOILING RESPONSE TO PRESSURE DECAY
Resumo
The paper presents the history of liquid superheat in a pool boiling system subjected to a sudden
pressure release. A 304 stainless steel heater surface in contact with distilled degassed water was monitored
during system pressure decay through a 1.00-inch orifice to the atmosphere. The data show that the
liquid superheat reaches a maximum during the initial transient pressure phase and becomes negative during
the final transient phase with release time of approximately 12 seconds. This phenomenon has not received
extensive publication in the literature and yet is quite probable in cryogenic systems.
