TEMPERATURE-CONTROLLED POOL-BOILING HEAT TRANSFER
要約
Characteristics of temperature-controlled pool-boiling heat transfer covering nucleate, transition and film boiling regions are studied for water at atmospheric pressure, A new computer-controlled experimental system is developed to realize stable operation in three boiling regions. Thermal hysteresis effects by increasing and decreasing heater temperature are found, for the first time, both in the nucleate boiling region and in the transition boiling region near the maximum heat flux point. Maximum heat flux of nucleate boiling and maximum heat flux of transition boiling are not the same. It is confirmed that the transition boiling is the combination of nucleate boiling and film boiling.
