Abstract
This paper presents Seawater pool nucleate boiling experiments were conducted to examine the difference of the fundamental process of pool nucleate boiling between the seawater and the distilled water. The nucleation site in the seawater experiments was less than that in the distilled water experiment. The decrease of the nucleation site affects inhibit of the boiling and the formation of secondary bubble, and the increase of the superheat of the heat-transfer surface. In the concentrated artificial seawater, the burnout was caused by the increase of the thermal resistance with the increase of the deposition thickness of the sea salt.
