Characteristics of Pool Boiling on a Heated Surface with Artificial Cavities - Effects of cavity arrangement and nucleation site interaction

摘要

Triple artificial cavities on heated surface have been performed to study a nucleation site interaction in pool boiling. This study aims to find out the existence of three effect interaction factors that found in twin artificial cavities. The preliminary results indicated that bubble coalescence factor and thermal interaction has effects in triple artificial cavities. Furthermore, the artificial cavities arrangement, intersite distance and pattern, also affected on bubble departure frequency and temperature fluctuation.
