Abstract
This study involved conducting subcooled flow boiling experiments using various different dissolved air concentrations in the Perfluorohexane (PFH) in order to clarify its effects on flow boiling heat transfer through a tube with an inner diameter of 4 mm, the following parameters were calculated and discussed excess temperature, boiling curve. Consequently, dissolved air was shown to affect boiling characteristics. In particular, dissolved air significantly affected the boiling curve in the low heat flux region, and the boiling curve was continuously decreased with increasing the effective heat flux for G = 300 [kg/m^2s], respectively. Also dissolved air significantly affect the onset of boiling.
