The effect of air injection into a subcooled water flow on boiling heat transfer and a critical heat flux (CHF) was examined. The heat transfer was remarkably improved by introducing an air flow into a water single-phase flow. The present results were well correlated with the Lockhart-Martmelli parameter where the vapor phase was replaced with the air phase. The CHF was improved a little by the air introduction in the high water flow region However, that was rather greatly reduced in the low flow region. The air introduction into the subcooled water flow was a more profitable way to get the better heat transfer with less pump power increase than increasing only the water flow rate.
