Impacts of salt concentration on nucleate pool boiling of NaCl solution

Salt solution pool boiling is of great significance in thermal engineering equipment, such as boilers and heat exchangers. Few researchers have been able to draw on systematic research into the impacts salt concentration transfer coefficients. This experimental work aimed understand role dissolved salts performance, which affected by surface wettability bubble dynamics. Pool experiment was conducted within a broad range concentration. The results show two different tendencies for heating surfaces. coefficient enhanced pin–fin while deteriorated bare increased. It indicated that promotes diameter nucleate density ∼13% 9%, respectively, strengthening hydrophobicity surface. Hence, strengthened.
